For any electrical crew working on cable networks — whether you’re cutting into a bundle at a substation, splicing conductors underground, or confirming phasing before energising a new feeder — the consequences of misidentification are serious. At best, you create an unplanned outage and a costly service call. At worst, you put people in immediate danger.

The problem is that modern cable networks are dense. Distribution cabinets are packed with conductors that look identical. Underground routes carry multiple circuits through the same trench. Even experienced technicians can’t rely on colour coding alone when cables age, documentation is outdated, or a bundle has been modified by a previous crew.

What you need is a tool that definitively tells you: this is the cable. Not approximately. Not probably. Definitively.

That’s exactly what the Megger DCI3 is built to do.

One System. Two Critical Functions.

The DCI3 is the first tool many utility crews, cable contractors, and network operators have encountered that combines cable identification and phase identification in a single, field-hardened unit — without requiring the cable to be de-earthed at any point during the process.

Cable Identification (CI Mode)

In CI mode, the DCI3 transmitter sends a high-current DC pulse — up to 25 A at 50 V DC — down the cable under test. A technician at the other end uses the RX3 receiver with a flexible inductive clamp to sweep the bundle and identify which cable is carrying the signal. The receiver provides 8 steps of amplification with a 27 dB dynamic range, giving clear discrimination even in tightly bundled installations or when cables run parallel for long distances.

The system works on de-energised low-, medium-, and high-voltage cables up to 30 km in length — covering most distribution network scenarios. For three-phase single-core cable sets, the DCI3 can identify all three phases in a single pass without reconnecting between phases, which is a significant time saving on larger jobs.

Live Cable Identification (LCI Mode — Optional)

With the optional LCI TX-440 transmitter module, the DCI3 extends its capability to energised low-voltage cables operating at 100–440 V AC. This is a genuine safety upgrade for crews working on live LV networks: rather than interrupting supply to identify a cable — which creates customer outages and requires switching authorisations — the transmitter connects phase-to-phase and injects a coded 80 A pulse at 30 pulses per minute. The receiver identifies the correct live cable without any interruption to the circuit.

This isn’t just a convenience feature. For utilities managing supply reliability KPIs or contractors working in occupied commercial buildings, being able to identify cables without de-energising can eliminate hours of coordination and disruption per job.

Phase Identification (PI Mode)

Phase identification is the other half of the puzzle. Before you join cables, connect busbars, or close a new feeder into an existing network, you need to confirm that the phases are correctly sequenced. Getting this wrong can destroy equipment, damage connected loads, or cause serious faults.

The DCI3’s phase identification mode uses passive CPIC50 clamps that clip over single-core cables while the cable ends remain grounded. The transmitter generates a signal in the 1 kHz–8 kHz band with automatic frequency selection, and the clamps detect which conductor carries which phase. For three-phase sets, all three conductors are identified simultaneously in a single measurement step — no swapping clamps, no reconfiguring.

For larger cable cross-sections or narrow switchgear cabinets where standard passive clamps won’t physically fit, the optional CPIC150-F active flexible clamps (150 mm diameter) handle the job without compromising accuracy.

Built for Real Field Conditions

The DCI3 transmitter is designed around the realities of utility and contractor work:

• IP54 rated (DIN EN 60529): Protected against dust ingress and water splashing from any direction. It will handle a wet trench, a dusty switching station, or a coastal substation without fuss.
• Operating range –10°C to +55°C: Works across Australian conditions from alpine winter sites to industrial environments in Queensland summer.
• Under 2 kg: Compact enough to carry to the worksite without it becoming a burden, yet robust enough to survive the transport case stack.
• 4.3″ colour touchscreen (480 × 272 WQVGA): Large, bright display at 425 cd/m² is readable in direct sunlight. The rotary encoder provides an alternative input method if you’re working in gloves.
• Li-Ion battery with 6+ hours CI runtime: A second battery is included in the standard kit, so if a job runs long you’re not hunting for a charger in the field. Fast recharge means the spare is ready for the next shift.

The modular TANOS transport case system keeps everything organised and protected. If your team eventually expands the DCI3 with additional clamp sets or the LCI module, the case stack grows with you — no need to start over with a new carry solution.

Modular by Design — Future-Proof by Default

The DCI3 is available in a range of configurations, and every system option can be retrofitted at any time. If you purchase a CI-only unit today and your scope of work expands to include phase identification or live LV cable work next year, you add the relevant module and a software licence — the base transmitter is already capable.

This modular architecture is particularly practical for Australian utilities and contractors who tender for different types of work across the year. Your capital investment in the DCI3 doesn’t become obsolete as your work scope changes.

Available software licences cover CI-only, PI-only, or combined CI+PI functionality depending on which option modules are fitted.

Applications Across the Australian Network Sector

Electrical Utilities and Distribution Network Service Providers (DNSPs) Identifying cables in crowded substations and distribution boards before planned maintenance or during fault rectification. Confirming phase sequence when energising new feeders or interconnecting substations. LCI mode allows identification on live LV feeders without interrupting supply to customers.

Underground Cable Contractors Locating the correct cable in a multi-circuit trench before cutting or jointing. Avoiding accidental damage to adjacent services during excavation or cable replacement. The 30 km identification range covers virtually all underground distribution runs.

Railway and Transit Electrification Identifying specific cables within complex signalling and traction power cable routes. Confirming correct phasing before connecting new sections of track supply or signalling systems, where a phase error could have serious operational consequences.

Renewable Energy — Solar and Wind Farms Confirming cable identity and phase sequence during AC collection system commissioning or O&M activities. Solar farms and wind projects frequently involve multiple identical cable runs between inverters, combiner boxes, and switchboards — the DCI3 eliminates guesswork at these connection points.

Industrial Facilities and Process Plants Identifying power cables in large motor control centres or distribution boards during planned shutdowns. Phase identification before connecting motor feeders or transformer secondaries to prevent costly equipment damage from phase reversal.

Infrastructure Projects During construction commissioning or handover, confirming cable identity and phasing across long runs between buildings or switchrooms. The DCI3 works at distances where other identification methods become unreliable.

TECHNICAL SPECIFICATIONS

TRADE-SPECIFIC USE CASES

Use Case 1 — DNSP Substation Cable Identification A distribution network crew needs to replace a 33 kV cable termination in a crowded substation where six similar single-core XLPE cables enter the same cable box. After de-energising, the DCI3 CI transmitter is connected at the remote end and the RX3 receiver scans the bundle at the substation end. The correct phase is identified in under two minutes, eliminating the risk of cutting the wrong cable and creating a second fault.

Use Case 2 — Live LV Cable Identification Without Outage A cable contractor is pulling a new circuit through an existing conduit in an occupied office building. Before cutting into a cable tray, they need to confirm which of six grey cables is the one to be disconnected. With the LCI TX-440 module, the transmitter is connected across phases at the board end and the receiver identifies the live cable without switching off any circuits. No tenants are affected.

Use Case 3 — Solar Farm AC Collection System Commissioning During commissioning of a large-scale solar farm near Mildura, the O&M team needs to confirm phase rotation for 24 identical underground AC cables running from string inverters to the main switchboard. The DCI3 PI mode with CPIC50 passive clamps checks all three phases of each cable simultaneously, with results documented for the IEC 62446-1 commissioning report. The job that previously took most of a day is completed in a few hours.

Use Case 4 — Railway Signalling Cable Identification A rail infrastructure contractor is decommissioning a section of signalling cable route and needs to positively identify specific cables among a multi-core bundle before cutting. The DCI3 CI mode with TFS CI twisted field sensor provides definitive identification at up to 30 km — well beyond the cable run length — without any risk of misidentification.

Use Case 5 — Underground Fault Repair in Urban Trench A street-works crew has excavated to repair a damaged cable. The trench contains four circuits in close proximity. Using the DCI3 CI mode, they confirm which cable is the faulted one before making any cuts, protecting the three healthy circuits and avoiding a second outage event that would have extended the incident into a public safety issue.

Use Case 6 — Industrial Motor Control Centre Phasing Before energising a new 415 V MCC feeder in a mining processing plant, the electrical team uses the DCI3 PI mode to confirm phase rotation at the incomer busbar matches the supply transformer. The passive CPIC50 clamps fit over the single-core cable tails while the system remains earthed, completing the check without any need to lift earths or expose live conductors.

Use Case 7 — Network Expansion — New Feeder Connection A DNSP is connecting a new underground feeder to an existing 11 kV ring main. Before the link box is closed, the DCI3 confirms that phase A, B, and C on the new cable align correctly with the existing network. Phase errors at this stage would cause a network fault at energisation — the DCI3 makes this a routine check rather than a risk.

What is a cable identification system used for?

A cable identification system is used to locate and confirm the identity of a specific cable within a bundle or group of cables — typically before cutting, jointing, or maintaining that cable. Field teams connect a transmitter to one end of the target cable and use a receiver with a detection clamp to scan the bundle at the other end, identifying which cable carries the transmitter’s signal. This prevents accidental cutting of the wrong cable, which can cause unplanned outages, equipment damage, or serious personal injury. The Megger DCI3 performs this function on de-energised cables up to 30 km in length across low-, medium-, and high-voltage systems.

---

What is the difference between cable identification and phase identification?

Cable identification confirms which physical cable in a bundle is the one you intend to work on — identifying it by number or label among multiple similar cables. Phase identification confirms which conductor in a multi-core or three-phase single-core cable set corresponds to Phase A, Phase B, and Phase C — ensuring correct phase rotation before the cable is connected into a network. Both are critical safety steps, but they answer different questions. The Megger DCI3 performs both functions from the same unit.

---

Can you identify cables without de-energising them?

Yes — with the right equipment. The Megger DCI3 with the optional LCI TX-440 module can identify energised low-voltage cables up to 440 V AC without interrupting the circuit. A transmitter is connected phase-to-phase and injects a coded signal; the receiver identifies the correct live cable at the other end. This is particularly valuable for urban distribution networks, occupied commercial premises, and any application where an outage would have significant operational or commercial consequences.

---

How is phase identification performed safely on grounded cable systems?

The Megger DCI3 uses passive clamp technology (CPIC50 clamps) that attaches to the outside of single-core cable conductors while the cable ends remain permanently earthed. The transmitter generates a low-level signal in the 1 kHz–8 kHz range and the clamps detect phase-specific signal characteristics without requiring the earth to be lifted at any point. This fundamentally changes the safety profile of the phase identification task — personnel are never exposed to conductors that have had their earth connection removed.

---

What does IP54 mean on a cable identification system?

IP54 is an ingress protection rating defined by IEC 60529 (DIN EN 60529 in the German standard). The first digit (5) indicates protection against dust ingress sufficient to prevent contact with internal parts, though not full dust exclusion. The second digit (4) indicates protection against water spray from any direction. For a cable identification system, IP54 means the unit can be used safely in outdoor environments, open switchyards, wet weather, and dusty switchroom conditions without risk of internal damage from environmental exposure.

Medium voltage cable infrastructure is the backbone of industrial facilities, utility networks, and renewable energy installations across Australia. When insulation degrades, faults develop, or commissioning sign-off is required, the testing process traditionally demands specialised, heavy equipment — and often more than one instrument. A withstand tester here, a tan delta analyser there, a separate sheath tester somewhere else. The logistics are slow, the cost is high, and coordinating multiple sets of gear on a live site creates unnecessary risk.

For electrical engineers, asset managers, and high-voltage test technicians who need fast, defensible results in the field, the status quo simply doesn’t cut it.

One System. Every Test You Need.

The Megger VLF Sine 37 kV changes the equation. Designed as a true all-in-one medium voltage cable diagnostic platform, it consolidates what traditionally required multiple instruments into a single portable unit small enough to transport in one piece. This isn’t a compromise — it’s the most powerful portable VLF tester in its class, capable of testing cables with capacitances up to 1.6 µF at 26 kVRMS and 0.1 Hz, which means cables exceeding 5 km present no challenge.

At just 29 kg, it delivers the highest test capacity in its class without the bulk of traditional HV test sets. It’s genuinely one-person portable, yet there’s no trade-off on power when testing long or heavily loaded cable circuits.

The system covers four core test disciplines out of the box:

• VLF withstand testing — using true sine wave voltage to stress cable insulation under controlled conditions
• DC testing — for applications where DC voltage is the required test method
• Sheath testing and fault pinpointing — up to -20 kV DC, fully compliant with IEC 60229, identifying sheath damage before it becomes a failure
• Internal tan delta diagnostics — available as an option, providing quantitative insulation condition assessment with automatic evaluation against IEEE 400.2 trending criteria

With the optional PDS 62-SIN partial discharge coupler, the system expands further into full PD diagnostics — making it a complete medium voltage cable test and diagnostic platform from a single, manageable package.

Smart Technology That Adapts to the Job

One of the most practical engineering decisions built into the VLF Sine 37 kV is its automatic frequency adjustment. As cable capacitance increases with cable length, maintaining a stable test voltage becomes more demanding. The system intelligently adjusts its test frequency — ranging from 0.01 Hz to 0.1 Hz — based on the connected cable’s capacitive load. On 15 kV-rated cables stretching to 25 km, the unit continues to deliver reliable, repeatable results without manual reconfiguration.

The output voltage is precisely controlled to ±1% accuracy across the full range (0–26 kVRMS in VLF sine mode, ±0–37 kV in DC mode), with 0.1 kV resolution. Source output current reaches 37 mA at 37 kVpeak, with measurement resolution down to 1 µA — the kind of precision that matters when you’re making asset management decisions based on leakage current trends.

Insulation resistance measurement extends up to 5 GΩ, covering the full range from healthy cable to severely degraded insulation.

For teams that need more than a pass/fail result, the optional internal tan delta module adds integrated insulation condition assessment to every VLF test — no second instrument, no second mobilisation. Quantitative dielectric loss measurements are evaluated automatically against IEEE 400.2 criteria, giving you a clear picture of cable health alongside the withstand result.

Built for the Field — No PC Required

High-voltage cable testing often happens in locations with no IT infrastructure, no comfortable desk, and no time for complicated software setups. The VLF Sine 37 kV addresses this directly. All test functions, data evaluation, and reporting are handled internally — the unit operates completely standalone without any external computer.

The 7-inch colour touchscreen interface is the heart of the user experience. Designed to minimise training time even for advanced diagnostic methods, it presents test parameters, live measurements, and evaluated results in a clear, logical workflow. Automatic result evaluation against IEEE 400.2 criteria means the unit interprets tan delta trends for you, flagging deterioration against both standard thresholds and user-defined trending limits.

Internal memory stores at least 1,000 measurements — a full season of fieldwork on a single unit. Results export via USB or LAN, with wireless connectivity on the roadmap. Crucially, historical measurements can be reviewed directly on the unit, allowing technicians to compare tests conducted months or years apart without needing to return to the office.

Safety Engineered In

Working with voltages up to 37 kV demands a test system with safety as a design priority, not an afterthought. The VLF Sine 37 kV includes automatic breakdown detection and automatic discharge of the test object after testing — removing the manual step that creates risk in the field. The system accepts a wide input voltage range (100–264 V, 50/60 Hz), making it compatible with Australian 230 V single-phase supplies as well as international site power.

The unit is rated IP21, operates across -20°C to +55°C, and stores safely between -20°C and +70°C — suitable for Australian conditions from alpine substations to outback solar farms.

HV test leads are available in 5, 10, or 15 m lengths, accommodating different site layouts, cable termination heights, and safe working distance requirements.

Expandable to a Full Diagnostic Platform

The modular architecture of the VLF Sine 37 kV means it grows with your testing requirements. The optional PDS 62-SIN PD coupler — the lightest partial discharge coupler available — attaches directly and transforms the system into a full withstand, tan delta, and PD diagnostic platform. When the job calls for pinpointing insulation weak spots rather than just assessing overall condition, this single add-on enables localisation of defects such as voids and water treeing without swapping instruments or reconfiguring your test setup. For sheath fault location, the system works in combination with the ESG NT2 step voltage probe using the 50 Hz voltage gradient method.

Additional accessories extend the system further: the HVCC leakage current correction module improves accuracy in challenging test environments, SF6 test adapters accommodate GIS-connected cable terminations, and optional external safety interlock units are available with or without remote operating controls.

Optional transport cases (including an IP67-rated variant) provide rugged protection during transit to and from site.

TECHNICAL SPECIFICATIONS

APPLICATION USE CASES

1. Commissioning New Medium Voltage Cable Circuits

Before energising a new 11 kV or 22 kV cable circuit, network operators and electrical contractors need documented proof of insulation integrity. The VLF Sine 37 kV performs a witnessed withstand test to the required voltage level, then generates an evaluated result stored internally for inclusion in the commissioning package. The single-unit approach eliminates the need to mobilise multiple instruments, reducing both cost and site coordination effort.

2. Condition Assessment of Aged XLPE and PILC Cable

Underground distribution cables don’t fail without warning — insulation deterioration follows a predictable path that tan delta measurement can detect. Using the optional internal tan delta module, maintenance engineers can trend dielectric loss factor over multiple test campaigns and compare results against IEEE 400.2 evaluation criteria. Early identification of deteriorating cable segments allows planned replacement rather than emergency restoration after an unplanned outage.

3. Post-Fault Recommissioning After Cable Repair

Following a cable fault and repair, network owners require re-testing before the circuit is returned to service. The VLF Sine 37 kV applies the required withstand voltage, monitors for breakdown, and delivers a pass/fail result with full data logging — providing the documentation needed for both internal records and regulator compliance.

4. Sheath Integrity Testing on Screened Cables

Damage to the outer sheath of screened medium voltage cables allows moisture ingress, which accelerates insulation ageing and ultimately causes failure. With built-in sheath testing capability to -20 kV DC, the VLF Sine 37 kV identifies compromised sheath integrity across the cable run. When combined with the ESG NT2 step voltage probe, the system pinpoints the exact fault location, dramatically reducing excavation scope and repair costs.

5. Routine Maintenance Testing for Industrial MV Networks

Manufacturing facilities, mining operations, and large commercial sites operating their own medium voltage networks need periodic cable testing to satisfy insurance requirements and internal maintenance standards. A portable, standalone system that requires no external computer or specialist IT support simplifies the process — one technician, one instrument, results on screen.

6. Solar Farm and Wind Energy Cable Infrastructure

Large-scale renewable energy installations in Australia rely on extensive medium voltage cable networks connecting inverters, transformers, and grid connection points. During construction, commissioning, and periodic O&M testing, the VLF Sine 37 kV provides the withstand and diagnostic capability needed across long cable runs in remote locations where generator power or limited 230 V supply may be the only available source.

7. Partial Discharge Diagnostics with PDS 62-SIN

When tan delta results indicate deterioration or a cable’s history warrants deeper investigation, connecting the optional PDS 62-SIN PD coupler upgrades the VLF Sine 37 kV to a full partial discharge diagnostic system. PD testing localises defects such as voids, contamination, and water treeing within the insulation — providing the actionable data needed to decide between continued service, accelerated monitoring, or cable replacement.

What is the Megger VLF Sine 37 kV used for?

The Megger VLF Sine 37 kV is a portable medium voltage cable test and diagnostics system. It performs four functions in a single unit: VLF withstand testing (sine wave and rectangular), DC withstand testing, cable sheath testing with fault pinpointing, and tan delta (dielectric loss) diagnostics. With the optional PDS 62-SIN coupler, it also performs partial discharge diagnostics. It is used by electrical engineers, high-voltage test technicians, and asset managers to commission new cables, assess aged insulation, and locate faults on cables rated up to 33 kV.

How heavy is the Megger VLF Sine 37 kV?

The Megger VLF Sine 37 kV weighs 29 kg (64 lbs) and measures 529 × 478 × 380 mm. It is described as the smallest and lightest unit in its class, making it portable for field deployment without lifting equipment. Optional wheeled or IP67-rated transport cases are available for vehicle transport and site-to-site movement.

What is the maximum cable length the VLF Sine 37 kV can test?

The VLF Sine 37 kV can reliably test 15 kV-rated cables up to 25 km in length. Its automatic frequency adjustment system varies the test frequency between 0.01 Hz and 0.1 Hz based on the connected cable’s capacitance, ensuring consistent performance across both short and very long cable runs without manual reconfiguration.

Does the Megger VLF Sine 37 kV evaluate results automatically?

Yes. The VLF Sine 37 kV automatically evaluates test results according to the IEEE 400.2 standard when the internal tan delta option is fitted. It classifies cable insulation condition based on measured tan delta values against standard thresholds and supports user-defined trending limits for customised condition monitoring programs. All results are stored internally and can be reviewed directly on the 7-inch colour touchscreen without a connected computer.

What standards does the Megger VLF Sine 37 kV comply with?

The Megger VLF Sine 37 kV supports testing and evaluation in accordance with IEEE 400.2 (VLF testing and tan delta evaluation of shielded power cables) and IEC 60229 (sheath testing). These are the primary international standards governing VLF cable withstand testing and diagnostics. Megger Germany holds ISO 9001 quality management certification, and an optional test/calibration certificate is available for the instrument.

The post Megger VLF Sine 37 kV | Medium Voltage Cable Test & Diagnostics System appeared first on rapid-tech.

For electrical contractors, network operators, and power utilities managing ageing medium voltage infrastructure, cable testing has long been a compromise between thoroughness and practicality. Bulky transformer-based test sets demand heavy lifting, external laptops, complex setup procedures, and often a second operator just to manage the equipment safely. Yet the stakes couldn’t be higher — an undetected insulation defect in a 11 kV or 22 kV distribution cable can trigger a network outage, expensive excavation, or worse.

What field teams need is a single instrument that does it all: voltage withstand, insulation diagnostics, and fault location — without needing a degree in cable diagnostics just to operate it.

The Megger VLF Sine Wave 62 kV was built to answer exactly that challenge.

What the VLF Sine Wave 62 kV Actually Does

At its core, this is a Very Low Frequency (VLF) test and diagnostic platform. Rather than applying the mains power frequency (50 Hz) at high voltage — which demands enormous transformer capacity — VLF testing uses frequencies between 0.01 Hz and 0.1 Hz. This dramatically reduces the reactive power required to stress a cable’s insulation, allowing a compact, portable unit to safely test cables rated up to 35 kV (with cable lengths up to 25 km).

The VLF Sine Wave 62 kV outputs up to 44 kV RMS (62 kV peak) sinusoidal AC, providing a waveform that closely mimics real power frequency stress on cable insulation — which is why IEEE 400.2 recognises VLF sine wave testing as the preferred diagnostic method for XLPE and EPR cable systems.

But this unit goes well beyond a simple “pass/fail” hipot tester. Here’s what it brings to the field in a single portable system:

VLF Withstand Testing Apply high-voltage AC stress at ultra-low frequency to verify cable insulation integrity post-installation or following a fault repair. The system handles test capacitances up to 10 µF, covering everything from short cable sections to extended underground feeders. Critically, the smart VLF system automatically adjusts the test frequency to match the cable length — no manual calculation required in the field.

Integrated Tan Delta (Dissipation Factor) Diagnostics With the optional internal tan delta module, the VLF Sine Wave 62 kV transitions from a withstand tester to a genuine cable health assessment tool. Tan delta (also known as loss factor or dielectric dissipation factor) measures the energy losses within a cable’s insulation, providing a sensitive early indicator of moisture ingress, thermal degradation, and insulation ageing — damage that a simple withstand test would miss entirely. Results are automatically evaluated against the latest IEEE 400.2 standard thresholds or user-defined trending limits, with the unit doing the interpretation so your team can make confident, documented decisions on-site.

DC Voltage Testing and Sheath Testing In addition to AC/VLF modes, the unit outputs DC voltage (±0–62 kV), supporting both DC withstand tests and cable sheath integrity testing to IEC 60229 at up to -20 kV DC. Sheath testing is essential for verifying the condition of the outer protective jacket — a frequently overlooked aspect of cable asset management — particularly after installation or mechanical disturbance.

Sheath Fault Pinpointing Combined with the optional ESG NT2 step voltage probe, the system can pinpoint the exact location of sheath faults using a pulsed DC signal. This eliminates guesswork and unnecessary excavation, saving significant time and cost for civil works crews.

Expandable to Full PD Diagnostics The VLF Sine Wave 62 kV doubles as a high-voltage source for the optional PDS 62-SIN partial discharge (PD) coupler. Once connected, this transforms the system into a comprehensive cable assessment platform capable of partial discharge detection, localization, and Phase Resolved PD Pattern (PRPD) analysis — all in compliance with IEC 60270. Partial discharge is widely regarded as the most reliable indicator of localised insulation defects that will ultimately cause cable failure; integrating PD capability alongside VLF testing means you can find not just weak insulation, but the exact location of the defect within the cable run.

Designed for the Field, Not the Laboratory

Megger designed the VLF Sine Wave 62 kV from the ground up for field deployment — and it shows.

Lightest in Class At 59 kg, this is among the lightest units available in the 62 kV VLF category. That matters on job sites with restricted access, where moving heavy equipment through plant rooms, substations, or along cable trenches is a genuine safety and logistics challenge.

No Laptop Required The entire test sequence — setup, execution, data capture, and result interpretation — runs on the unit itself via a large 7-inch colour touchscreen. The intuitive interface keeps training time low and reduces the risk of operator error, even for less experienced test personnel. All measurements are stored internally (capacity for at least 1,000 test records), and data can be exported via USB or LAN for report generation using the included Megger Book Lite software.

Continuous Duty Cycle The VLF Sine Wave 62 kV operates on a continuous duty cycle — meaning there’s no need to pause for equipment cool-down between tests. For teams working through multiple cable bays in a substation or testing a long cable route section by section, this is a practical time-saver.

Wide Input Voltage Range The unit accepts any supply from 100 V to 264 V at 50 or 60 Hz, making it compatible with Australian 230 V / 50 Hz supply as well as generator power sources commonly used on remote or construction sites. An Australian mains cable (order no. 90020435) is available to ensure correct plug compatibility.

Built for Australian Conditions With an operating temperature range of -20 °C to +55 °C and IP 21 ingress protection, the VLF Sine Wave 62 kV handles the environmental demands of Australian infrastructure work — from hot coastal substations to alpine cable routes.

Safety Is Non-Negotiable

Working at voltages up to 62 kV demands uncompromising safety features. The VLF Sine Wave 62 kV incorporates:

• Automatic discharge of the test object — once a test concludes, the system automatically discharges residual stored energy in the cable under test. This is not optional; it’s built into every test sequence.
• Analogue residual voltage indicator — a physical, always-visible indicator that shows the operator the cable’s charge status at all times, independent of software. No need to trust a screen readout when deciding whether it’s safe to disconnect.
• Breakdown detection — the unit detects cable breakdown events and handles them safely, protecting both the operator and the equipment under test.
• External safety unit option — for high-risk testing environments, an optional external safety unit (with or without operating controls) provides additional interlock capability for multi-person or remote test setups.

These features align with the safety obligations under AS/NZS 3000 and Safe Work Australia electrical safety guidelines, supporting the duty-of-care requirements that every electrical contractor and asset owner carries when working on live or recently energised medium voltage infrastructure.

Reporting and Compliance Documentation

In the Australian market, test documentation is increasingly central to asset management compliance, insurance requirements, and regulatory obligations. The VLF Sine Wave 62 kV makes reporting straightforward:

• All test data is automatically stored on the unit’s internal memory
• Datasets export via USB or LAN to the included Megger Book Lite PC software
• Results include automatic interpretation against IEEE 400.2 criteria, reducing the subjectivity in post-test reporting
• Wireless data transfer is planned for a future firmware update, further streamlining field-to-office workflows
• Optional Megger Book 3 full-licence software (order no. 2015875) provides advanced analysis and report customisation capabilities for organisations with rigorous asset condition reporting requirements

TECHNICAL SPECIFICATIONS TABLE

APPLICATION USE CASES

1. Post-Installation Acceptance Testing — Underground Distribution Cables

After laying a new 11 kV or 22 kV XLPE underground cable for a residential subdivision or industrial estate, the installing contractor uses the VLF Sine Wave 62 kV to perform a VLF AC withstand test before energisation. The unit automatically adjusts frequency to the cable’s capacitance, runs the prescribed test duration, and stores a timestamped record — providing the network owner with documented proof of insulation integrity prior to connection.

2. Predictive Maintenance Diagnostics — Ageing Cable Networks

A state-based electricity distributor managing ageing PILC (paper insulated lead covered) or early-generation XLPE feeders uses the tan delta module to build a condition baseline across its cable asset register. By trending dissipation factor values year-on-year against IEEE 400.2 limits, maintenance planners can prioritise cable replacement based on actual condition data rather than age alone — reducing both capital expenditure and unplanned outage risk.

3. Post-Fault Repair Verification — Industrial Plant

Following an insulation fault and cable repair in a 6.6 kV industrial plant, the maintenance team performs a DC withstand test and tan delta measurement before reconnecting the cable. The automatic result interpretation confirms whether the repair is sound, providing documented evidence for both internal records and insurer requirements under AS/NZS 3000 compliance obligations.

4. Sheath Integrity Testing — New Cable Routes

A civil and electrical contractor installs a 22 kV cable through conduit across a major road crossing. Before backfilling, the sheath is tested at -10 kV DC to confirm no damage occurred during installation. Any sheath breakdown detected at this stage is rectified before reinstatement, avoiding costly road excavation later.

5. Sheath Fault Pinpointing — Service Restoration

A fault location team is called to investigate a sheath fault alarm on a 33 kV transmission cable. Using the pulsed DC mode in conjunction with the optional ESG NT2 step voltage probe, the team walks the cable route and pinpoints the fault location to within the accuracy of the system — dramatically reducing the excavation footprint and service restoration time.

6. Full Cable Diagnostics — Expanded PD Testing

A power utility deploying the optional PDS 62-SIN coupler uses the combined system to perform simultaneous VLF withstand, tan delta, and partial discharge measurements on a 22 kV feeder suspected of moisture ingress. The PRPD patterns generated by the PD coupler enable the test team to distinguish between corona activity at terminations (benign) and internal PD at a mid-route joint (actionable) — preventing a misdiagnosis that could have led to premature cable replacement or, worse, an in-service failure.

7. Test Reporting and Compliance Documentation

Asset managers and test engineers across Australian electricity networks use the Megger Book Lite or Megger Book 3 software to generate structured test reports from VLF Sine Wave 62 kV data exports. These reports provide the documentation trail required for asset management systems, regulatory reporting, and audit defence — particularly relevant for NSPs (network service providers) operating under AER compliance frameworks.

What is a VLF cable tester used for?

A VLF (Very Low Frequency) cable tester is used to test the insulation integrity of medium voltage underground power cables. It applies a high-voltage AC test signal at a very low frequency (typically 0.01–0.1 Hz) rather than the normal power frequency (50 Hz), which dramatically reduces the reactive power required. This allows a compact, portable unit to safely perform withstand testing, insulation diagnostics (tan delta), and sheath testing on cables rated from 6.6 kV up to 35 kV. VLF testing is recognised by IEEE 400.2 as a preferred method for XLPE and EPR cable system assessment.

What is the difference between VLF withstand testing and tan delta testing?

VLF withstand testing applies a high voltage to the cable insulation to verify it can withstand operating stress without failing — it produces a pass/fail result. Tan delta testing (also called dissipation factor testing) measures the dielectric losses in the insulation at near-service voltage levels, providing a quantitative indicator of insulation condition, moisture ingress, and ageing. Withstand testing proves integrity; tan delta testing assesses health and predicts future risk. The Megger VLF Sine Wave 62 kV can perform both tests, with the optional internal tan delta module evaluated automatically against IEEE 400.2 criteria.

How long can a cable be tested with a VLF 62 kV tester?

The Megger VLF Sine Wave 62 kV can test cables with a capacitance up to 10 µF. For a typical 22 kV, 95 mm² XLPE cable (around 0.4 µF/km), this corresponds to approximately 25 km of cable length. The unit’s smart frequency adjustment automatically selects the appropriate test frequency based on the measured cable capacitance, making long-cable testing straightforward without manual calculation.

What does tan delta tell you about a cable’s condition?

Tan delta (also known as dissipation factor or loss angle) measures the ratio of resistive to capacitive current flowing through a cable’s insulation under an applied voltage. A low tan delta value indicates healthy, dry insulation. Elevated or increasing tan delta values indicate insulation degradation, moisture ingress, thermal damage, or contamination. IEEE 400.2 provides diagnostic thresholds: cables with tan delta above defined limits or showing increasing trend values are flagged for closer monitoring or planned replacement, allowing asset managers to act before an in-service failure occurs.

Can a VLF tester perform partial discharge testing?

A standard VLF tester provides the high-voltage source needed for partial discharge (PD) measurements, but PD detection requires a separate PD coupler connected in parallel with the cable under test. The Megger VLF Sine Wave 62 kV is designed to work with the optional Megger PDS 62-SIN PD coupler, creating a combined system that delivers VLF AC voltage while simultaneously measuring, localising, and classifying partial discharge activity in real time. This combined approach enables both withstand testing and full PD diagnostics in a single field deployment.

What safety features does the Megger VLF Sine Wave 62 kV have?

The Megger VLF Sine Wave 62 kV incorporates three core safety mechanisms. First, an automatic discharge circuit discharges the test object (cable) at the end of every test cycle, eliminating residual stored energy risk. Second, a physical analogue residual voltage indicator provides a hardware-level, always-visible display of the cable’s charge status — independent of the touchscreen — so the operator can confirm safe discharge before disconnecting. Third, breakdown detection circuitry identifies cable insulation failure events and handles them safely. An optional external safety unit with interlock capability is also available for multi-operator or restricted-access test environments.

If your lab handles a mix of multimeters, clamp meters, power meters, and insulation testers, you’ve probably lived with the compromise: multiple reference sources, multiple setups, multiple opportunities for error.

Swapping between instruments mid-calibration wastes time, introduces connection uncertainty, and makes automated workflows unnecessarily complex. Add oscilloscope calibration to the mix and you’re looking at a second (or third) piece of kit occupying valuable bench space.

The Meatest 9020 Multifunction Calibrator is designed to eliminate that bottleneck. It consolidates the output functions your lab needs most — AC/DC voltage and current, resistance, capacitance, power, energy, temperature simulation, and frequency — into a single, rack-mountable reference instrument with a 9 ppm basic uncertainty.

For labs servicing everything from handheld DMMs to 6½-digit bench meters, it covers the full workload without the clutter.

One Instrument. Your Entire Electrical Calibration Workload.

The 9020 is built around a broad-coverage output architecture designed for the realities of a mixed-instrument calibration lab. Here’s what it sources:

AC/DC Voltage (0 mV – 1050 V) Covers both DC and AC sine from 1 mVRMS to 1050 VRMS, with non-sine waveforms (sawtooth, triangle, square, truncated sine) available up to 200 VRMS. DC basic uncertainty is as low as 8 ppm of value on the 20 V range — suitable as a reference for all but the most demanding 8½-digit DMM calibrations. AC uncertainty runs to 160 ppm across the primary range. Frequency accuracy is 5 ppm with 5-digit resolution across the 3 Hz – 300 kHz span.

AC/DC Current (0 µA – 30 A) The 9020 pushes current output to 30 A — making it well suited for calibrating high-range clamp meters used by industrial maintenance teams and energy monitoring specialists. With the optional 0950 Current Coil accessory, simulated current scales to 1500 A with a 45–65 Hz frequency range and 0.3 % additional uncertainty. DC current uncertainty is as low as 100 ppm on the mid-ranges, with AC uncertainty from 300 ppm at standard frequencies.

Resistance & Capacitance Variable resistance simulation from 0 Ω to 1.1 GΩ with 6½-digit resolution and uncertainty as tight as 15 ppm (1 kΩ–100 kΩ fixed standards). Capacitance sources from 600 pF to 120 mF with 0.15% uncertainty across the primary range. Both 4-wire (Kelvin) and 2-wire modes are supported, with dedicated 2W-COMP mode for compensated 2-wire measurements.

AC/DC Power & Energy (40 µW – 31.5 kW) Power calibration spans DC to 1000 Hz across voltage and current combinations from 0.2 V/0.2 mA up to 1050 V/30 A. Phase shift uncertainty is 0.15° to 200 Hz. Total power accuracy on a 230 V/50 Hz EU grid with a 1 A load is 0.069 % of value — highly competitive for calibrating energy meters and power analysers used in sub-metering, solar PV monitoring, and industrial energy management. Harmonic distortion capability covers 50 harmonic products (15–1000 Hz fundamental), making the 9020 directly applicable to testing power quality instruments against harmonic content requirements.

Temperature Simulation (RTD & Thermocouple) RTD simulation supports Pt385, Pt3916, Pt3926, Ni672, Cu427, Cu428, and custom curves with R0 range 20 Ω–2 kΩ. Uncertainty is 0.01–0.07 °C. Thermocouple support covers types A, B, C, D, E, G, J, K, L, M, N, R, S, T, U, and XK, with manual or automatic cold junction compensation via Adapter 91. TC uncertainty ranges 0.05–0.55 °C — adequate for calibrating all common industrial temperature instruments.

Frequency (0.1 Hz – 2 MHz) Square-wave frequency output at 100 mVpk, 1 Vpk, or 3 Vpk with 5 ppm accuracy and duty cycle control (0.1%–99.9%). Suitable for calibrating frequency-input process meters, panel instruments, and data loggers.

Built-In Process Multimeter

An optional internal measurement module (MER option) allows the 9020 to simultaneously source a stimulus signal and measure the device under test’s output — critical for calibrating transducers, loop-powered process transmitters, and industrial sensors. The built-in meter covers DC voltage (0–12 V), DC current (0–24 mA), resistance (0–20 kΩ), RTD and thermocouple temperature, and frequency (1 Hz–100 kHz).

This simultaneous source-and-measure capability simplifies transducer calibration workflows considerably and supports simulation of strain gauges and other bridge-type sensors via the 9000-60 cable accessory.

Oscilloscope Calibration Options

Two scope calibration options extend the 9020’s frequency output into the RF domain:

• SCO option: Levelled sine output to 400 MHz, pulse/time marker to 400 MHz, trigger output, and input impedance measurement (100 Ω / 2 MΩ). Amplitude uncertainty 0.5% + 350 µVpk at low frequency, extending to 3.7% at 400 MHz. Jitter < 2 ns, rise time < 1 ns.
• SC1 option: Extends levelled sine to 1.1 GHz (amplitude range 1.4 mVpk–1.5 Vpk to 1 GHz; 1.4 mVpk–1 Vpk above 1 GHz). Frequency uncertainty drops to 0.1 ppm in pulse/time marker mode.

These options make the 9020 one of the few compact multifunction calibrators capable of supporting both bench instrument calibration and oscilloscope bandwidth verification from a single chassis.

High Voltage Resistance for Insulation Tester Calibration

The HVR option adds a dedicated high-voltage resistance output specifically designed for verifying insulation resistance testers and megaohmmeters. Resistance range spans 100 kΩ to 100 GΩ with test voltages to 1500 VDC. This is directly relevant to Australian labs calibrating instruments used under AS/NZS 3000 compliance programs, electrical safety testing, and NATA-accredited electrical calibration services. Resistance uncertainty is 0.2–3% depending on range; test voltage uncertainty 0.3%–1.5% + 5 V.

Automation and Lab Integration

The 9020 ships with RS-232, IEEE-488 (GPIB), USB, and Ethernet interfaces as standard — making it straightforward to integrate with existing automated calibration platforms. For labs using Meatest’s own WinQbase or Caliber software, the 9020 supports the CamOCR optical readout module, which allows semi-automated calibration of instruments with no remote control interface — useful for legacy analogue meters and older DMMs. A full communication API is documented in the user manual for custom automation development.

Preset storage allows senior technicians to define verified output configurations that less experienced operators can recall and execute, reducing human error in high-throughput calibration environments.

Why It Suits Australian Calibration Labs

Australian labs operating under NATA accreditation requirements need calibration sources with traceable uncertainty chains that clearly support the instruments under test. The 9020’s 12-month stability specifications — stated at 95% confidence, k=2 — satisfy the rigorous uncertainty budgeting requirements of ISO/IEC 17025.

Its coverage of insulation resistance (to 1.5 kV), power (AC/DC to 1050 V/30 A), and temperature simulation means a single instrument can support calibration of the test equipment categories most commonly used by Australian electrical contractors, industrial maintenance teams, and compliance testers working to AS/NZS 3000, AS/NZS 3017, and related standards.

For calibration businesses and in-house labs looking to reduce instrument capital while maintaining accreditation-ready uncertainty performance, the 9020 represents a compelling consolidation investment.

USE CASES

1. NATA-Accredited Electrical Calibration Laboratories

The 9020’s 9 ppm DC voltage accuracy and comprehensive multi-function output make it a primary reference source for calibrating multimeters, clamp meters, and bench DMMs across the full workload of a general electrical calibration lab.

Its IEC 61010 safety compliance and traceable uncertainty specifications align directly with ISO/IEC 17025 accreditation requirements.

2. Power Analyser and Energy Meter Calibration

With AC/DC power output to 31.5 kW (1575 kW with optional 0950 Current Coil), phase shift uncertainty of 0.15° to 200 Hz, and 50-harmonic generation capability, the 9020 is well-suited to calibrating single and three-phase power analysers, revenue-grade energy meters, and power quality instruments used in industrial sub-metering and solar PV grid connection applications.

3. Industrial Transducer and Process Meter Calibration

The optional MER module enables simultaneous sourcing and measurement, supporting the calibration of loop-powered 4–20 mA transmitters, pressure and temperature transducers, and process meters. Combined with RTD and thermocouple simulation, this makes the 9020 valuable for industrial maintenance calibration teams in manufacturing, resources, and utilities sectors.

4. Oscilloscope Bandwidth Verification

With the SCO (400 MHz) or SC1 (1.1 GHz) option, the 9020 extends into oscilloscope calibration territory — delivering levelled sine signals, pulse/time markers, trigger outputs, and input impedance measurement from the same chassis that handles DC voltage reference work.

This suits calibration service providers who need oscilloscope capability without a dedicated RF calibrator.

5. Insulation Tester and Megohmeter Calibration

The HVR option provides test voltages to 1500 VDC with resistance simulation from 100 kΩ to 100 GΩ — directly addressing the calibration requirements for insulation resistance testers (Meggers) used across Australia’s electrical contracting, industrial, and infrastructure sectors, where compliance with AS/NZS 3000 and AS/NZS 3760 is mandatory.

6. Electrical Safety Test Equipment Calibration Services

Calibration service providers offering certificate-of-calibration services to electrical contractors, facilities managers, and industrial clients can use the 9020 to support PAT tester, loop tester, and installation tester calibration programmes. The instrument’s broad output coverage reduces the number of reference sources required and simplifies multi-function service delivery.

Australia’s solar sector has grown dramatically. Utility-scale and commercial rooftop installations operating at 1000 V and above are now the norm, with 1500 V DC string systems increasingly common on large ground-mount and commercial-scale arrays.

The challenge? Most general-purpose clamp meters and multimeters are rated to CAT II or CAT III 1000 V — meaning they simply aren’t equipped for the transient overvoltages that can occur in these higher-voltage environments.

Using an under-rated instrument on a high-voltage PV array isn’t just a compliance issue — it’s a genuine electrocution risk. IEC 61730-1 (the standard for PV module safety qualification) explicitly classifies solar installations as Measurement Category III environments. If your instrument doesn’t match the category and voltage of the site, you’re working outside its safe operating envelope.

That’s the problem the HIOKI P2010 DC High Voltage Probe was designed to solve.

What the HIOKI P2010 Does

The P2010 is a DC high voltage probe accessory that plugs directly into compatible HIOKI clamp meters and digital multimeters via standard 4 mm banana terminals. Once connected, it upgrades the instrument’s measurement capability to CAT III 2000 V DC — pushing the voltage ceiling well beyond what most standalone meters can handle.

It works by scaling the input voltage through a precision 20 MΩ resistive divider network, delivering a proportionally reduced output signal to the connected meter. Depending on the instrument, the P2010 operates in either “DC High V Probe Mode” (for compatible clamp meters like the CM4373-50 and CM4375-50, and the DT4261 DMM) or “1/10 output rate mode” (for other compatible HIOKI DMMs).

The key point: the probe does the heavy lifting — handling the dangerous high-voltage input — while the meter simply reads the scaled output. The result is a measurement chain that’s safe, compliant, and accurate at voltages your standard test leads can’t touch.

Built for Australian Solar Professionals

For solar installers and commissioning engineers working to AS/NZS 5033 (Installation and Safety Requirements for PV Arrays) and IEC 62446-1 (Grid-Connected PV Systems — Minimum Requirements for Documentation, Commissioning Tests and Inspection), correct instrument categorisation is a fundamental requirement.

The P2010’s CAT III 2000 V rating satisfies the overvoltage category requirements for PV string and combiner testing in large commercial and utility installations.

CEC accredited designers and installers working on systems with string voltages above 1000 V will find the P2010 fills a genuine gap in their test kit — it’s the accessory that makes a capable HIOKI clamp meter or DMM fully PV-system capable.

Key Benefits

Measurement Safety Without Compromise The P2010 carries a CAT III 2000 V rating — the same category as solar PV installations per IEC 61730-1. Overload protection is rated to 2200 V DC/AC for one minute between the input terminals. You’re not working at the ragged edge of your instrument’s limits; you have genuine safety margin built in.

Non-Intrusive Measurement — No System Shutdown Required One of the practical advantages of voltage probing over current-injection testing is that you can take live measurements without interrupting generation. The P2010 allows high-voltage DC string and array measurements while the system remains connected and generating. This is valuable for fault-finding, commissioning verification, and regular maintenance inspections without costly downtime.

Extends Your Existing HIOKI Instrument Investment If your team already carries HIOKI CM4373-50, CM4375-50, CM4371-50, CM4141-50, or DT4261/DT4281/DT4282 instruments, the P2010 is the most cost-effective way to add high-voltage PV measurement capability. You don’t need to purchase a dedicated high-voltage meter — the P2010 transforms your existing instrument into a fully rated 2000 V DC measurement solution.

Wide Operating Temperature Range Solar work happens outdoors, often in harsh Australian conditions. The P2010 operates from –25°C to +65°C, making it equally capable during a crisp winter commissioning job in the Victorian Alps or summer maintenance work on a rooftop array in Darwin.

Precision Input Resistance The 20 MΩ ±5.0% input resistance ensures the probe draws negligible current from the circuit under test — important when working with string configurations where load disturbance can affect readings and potentially trigger protection equipment.

Compatible Instruments

The P2010 is compatible with the following HIOKI instruments. Note that connection modes differ:

DC High V Probe Mode (direct 2000 V range):

• CM4141-50 AC Clamp Meter
• CM4371-50 AC/DC Clamp Meter
• CM4373-50 AC/DC Clamp Meter
• CM4375-50 AC/DC Clamp Meter
• DT4261 Digital Multimeter

1/10 Output Rate Mode (scaled reading):

• DT4252, DT4253, DT4255, DT4256
• DT4281, DT4282

Note: The P2010 requires a compatible HIOKI clamp meter or DMM, purchased separately. Always confirm your instrument model before ordering.

Application Use Cases

1. Utility-Scale and Commercial Solar PV Commissioning When commissioning a large-scale solar installation with string voltages at or approaching 1500 V DC, AS/NZS 5033 and IEC 62446-1 require measurement of open-circuit voltage and operating voltage for each string.

The P2010 makes this task safe and straightforward — connect to your HIOKI clamp meter or DMM and verify string voltages with a CAT III rated instrument without improvised workarounds.

2. Fault Diagnosis on High-Voltage PV Strings String-level faults — failed bypass diodes, shading losses, degraded modules — often require live voltage measurements across strings and sub-arrays to isolate the fault. The P2010 allows this diagnostic work to be performed at full system voltage with confidence, without needing to de-energise the array.

3. Combiner Box and DC Distribution Inspections Combiner boxes on utility installations can see bus voltages above 1000 V DC. Verifying bus voltage, checking string input voltages, and confirming fuse/circuit breaker operation all require high-category measurement tools. The P2010 combined with a compatible HIOKI clamp meter gives technicians the right instrument for the task.

4. Maintenance Inspections on Aging Installations As Australia’s early large-scale solar installations approach 10+ years of operation, scheduled maintenance and performance inspections are increasingly common. Measuring degradation trends in string output voltage requires repeatable, accurate, high-voltage capable measurements — exactly what the P2010 delivers.

5. Safety Audits and Compliance Verification Safety officers and accredited auditors verifying PV system installations against AS/NZS 5033 or IEC 62446-1 need to document voltage measurements made with correctly rated instruments. The P2010’s CAT III 2000 V rating ensures the measurement chain meets the overvoltage category requirements specified in the applicable standards.

Q: What is the HIOKI P2010 used for? The HIOKI P2010 is a DC high voltage probe accessory used to extend the voltage measurement capability of compatible HIOKI clamp meters and digital multimeters to 2000 V DC with a CAT III safety rating. It is primarily used for safe inspection, commissioning, and maintenance of high-voltage solar PV installations, including large-scale systems operating at 1500 V DC.

Q: What CAT rating do I need to measure solar PV installations? According to IEC 61730-1 (PV module safety qualification standard), solar PV installations are classified as Measurement Category III (CAT III) environments. Any instrument or probe used for voltage measurement on PV strings, combiners, or arrays must carry a CAT III rating appropriate to the system voltage. For modern 1500 V DC systems, a CAT III 1500 V or higher rating is required.

Q: Is 2000 V measurement safe for a 1500 V solar installation? Yes. Using a 2000 V rated probe like the HIOKI P2010 on a 1500 V DC solar installation provides a safe margin above the system’s operating voltage. The CAT III 2000 V rating also accounts for transient overvoltages — voltage spikes that can significantly exceed the nominal system voltage during switching events or fault conditions.

Q: Can I use my standard multimeter on a 1500 V solar installation? Standard multimeters rated to CAT III 1000 V or CAT II 1000 V are not suitable for direct measurement on solar PV strings operating at or above 1000 V DC. You either need a dedicated high-voltage meter, or an accessory like the HIOKI P2010 that extends a compatible meter’s rating to CAT III 2000 V.

You’re mid-diagnosis, current clamp in hand, and your oscilloscope is ready to go — except the clamp outputs banana plugs and the scope only takes BNC. It’s a mismatch that kills momentum, especially when you’re under the bonnet of a vehicle or working to a tight service schedule.

This isn’t a niche problem. Automotive oscilloscopes from brands like Hantek, PicoScope, and TiePie are BNC-input instruments, while a huge range of current clamps, breakout leads, and test accessories terminate in the universal 4mm banana format. Without the right adapter, you’re either hunting for a workaround or pulling out a completely different lead set.

The PJP 7043-IEC solves this problem outright.

What the PJP 7043-IEC Actually Does

The 7043-IEC is a purpose-built signal adapter manufactured by Electro-PJP — a French brand with decades of pedigree in precision test accessories. It converts a single male BNC connector (oscilloscope end) into two female 4mm banana sockets (red and black), allowing any banana-terminated test lead or current clamp to plug directly into a BNC-input instrument.

The colour-coded sockets (red positive, black negative/ground) eliminate polarity confusion — critical when you’re reading waveforms and signal orientation matters. Both the BNC plug and the 4mm sockets are fully shrouded, so there’s no exposed live metal during connection or disconnection.

It’s compact, it’s robust, and once you have one in your kit, you’ll wonder how you ever managed without it.

Where This Adapter Earns Its Keep

Automotive Diagnostics This is the 7043-IEC’s home territory. Pair it with the TCA 60 (60 A) or TCA 600 (600 A) current clamps and you’ve got a non-invasive current measurement path straight into your automotive oscilloscope. Starter motor current draw, injector waveforms, alternator output — all readable without breaking into the circuit. Perfect for auto electricians and automotive technicians doing first-look diagnostics.

Electrical Trade & Maintenance Electricians and industrial maintenance technicians who use oscilloscopes for waveform capture on motor drives, inverters, or switchgear can use this adapter to bring standard banana-plug current probes into their scope’s BNC input. Saves carrying multiple lead sets to site.

Lab & Bench Testing Electronics technicians and R&D engineers working on benches equipped with BNC-input oscilloscopes can use the 7043-IEC to interface any 4mm banana test probe or current transducer without signal compromises. The adapter’s compact form factor keeps bench clutter to a minimum.

Training & Education TAFEs, RTOs, and university engineering labs typically stock a mix of equipment — oscilloscopes with BNC inputs alongside current clamps and multimeter leads with 4mm terminations. The 7043-IEC bridges the gap cleanly, reducing the number of adapter cables that need to be stocked.

Field Service & Calibration Calibration technicians who carry portable oscilloscopes alongside calibrated current sources or clamps will find this adapter fits neatly in a carry case. Rated to IEC 61010-031:2015 (500 V CAT I / 150 V CAT III), it handles typical indoor field service signal measurement with the appropriate insulation class. Note: this adapter is rated for indoor use only — it is not intended for outdoor or exposed-environment deployment.

Technical Specifications

Compatibility — What It Works With

The PJP 7043-IEC is a universal adapter designed to work with:

• Oscilloscopes with BNC inputs: PicoScope automotive, Hantek series, TiePie, Rigol, Keysight, Tektronix, and most bench and automotive scopes
• Current clamps with 4mm banana outputs: Including the TCA 60 (60 A) and TCA 600 (600 A) automotive current clamps
• Double banana plugs and component holders: The 19 mm (¾ inch) socket spacing is the standard double banana pitch, so it accepts double banana plugs directly
• Breakout leads and breakout boxes with 4mm banana terminations
• Standard multimeter-style test leads in situations where scope input is needed
• Current transducers and signal output probes terminated in 4mm format

It is not a power adapter — the 3 A current limit means it’s designed for instrumentation signal paths, not high-current power connections. It is also rated for indoor use only.

Frequently Asked Questions

What is the PJP 7043-IEC used for? The PJP 7043-IEC is a signal adapter that lets you connect test accessories with 4mm banana plug outputs — such as current clamps, breakout leads, or test probes — directly to an oscilloscope or measuring instrument with a BNC input. It’s widely used in automotive diagnostics, electronics testing, and lab environments.

Will the PJP 7043-IEC work with my PicoScope or Hantek automotive oscilloscope? Yes. The 7043-IEC fits any standard BNC input, including those on PicoScope, Hantek, and TiePie automotive oscilloscopes. It’s specifically designed for this type of application — connecting 4mm banana-terminated current clamps to BNC-input scopes.

What current clamps is this adapter compatible with? It works with any current clamp that outputs a 4mm banana plug signal, including the TCA 60 (60 A) and TCA 600 (600 A) automotive current clamps. It’s also compatible with other 4mm banana-output current transducers and signal probes within the 3 A signal path limit.

Is the PJP 7043-IEC safe to use in automotive environments? Yes. The adapter is rated to IEC 61010 500 V CAT I and 150 V CAT III with reinforced insulation, pollution degree 2. For automotive 12 V / 24 V systems and signal measurement work, this rating is appropriate. Both the BNC plug and banana sockets are fully shrouded for safe connection.

Can I use this adapter for mains voltage measurements? No. The adapter carries a 500 V CAT I rating and 150 V CAT III rating. CAT I covers electronics circuits only — it is not rated for direct connection to mains supply circuits (which require CAT II at minimum). It is also rated for indoor use only. Use this adapter for signal-level and low-voltage measurement paths in indoor environments only.

Why are the banana sockets colour coded red and black? The red socket is positive and the black socket is the negative/reference (ground). Colour coding ensures you connect your leads in the correct polarity, which matters when capturing waveforms where phase or polarity is significant — such as current direction on an injector circuit or motor winding.

Is the PJP 7043-IEC the same as the PJP 7043 (without IEC)? The “IEC” suffix indicates that this version meets IEC 61010 safety standards with reinforced insulation. If you’re using this in any professional, trade, or compliance-relevant environment, the IEC variant is the correct choice.

How compact is this adapter? Will it fit in a tool case? The 7043-IEC is a small adapter — 63 mm total length (20 mm BNC section + 43 mm body), 19 mm wide at the banana socket end, and weighing just 0.029 kg. It fits easily into a test lead pouch or tool case alongside your oscilloscope leads and current clamps.

What adapter connects a current clamp to an oscilloscope? A BNC to 4mm banana adapter — such as the PJP 7043-IEC — connects a current clamp with 4mm banana plug outputs to an oscilloscope with a BNC input. The adapter converts the BNC socket on the scope into two female 4mm banana ports (red and black), allowing direct connection of current clamps, breakout leads, and probes. This is the standard solution used in automotive diagnostics and electronics bench work.

What is a BNC to banana adapter used for in automotive diagnostics? In automotive diagnostics, a BNC to banana adapter is used to connect current clamps (which output 4mm banana plugs) to automotive oscilloscopes (which have BNC inputs). This allows technicians to capture current waveforms — such as injector current ramp, starter motor draw, or alternator output — directly on the oscilloscope without modifying cables or circuits. The PJP 7043-IEC is a purpose-built example of this type of adapter.

Is the PJP 7043-IEC compatible with PicoScope? Yes. The PJP 7043-IEC plugs directly into any standard BNC input, including those on PicoScope automotive diagnostic oscilloscopes. It gives you two female 4mm banana sockets, enabling current clamps and 4mm banana-terminated probes to connect straight to the scope. It’s fully insulated, CE approved, and rated to IEC 61010 for safe professional use.

The Problem With Most Earth Resistance Testing on Australian Sites

Ask any sparkie who’s spent time doing earthing compliance work what frustrates them most and you’ll hear the same answers: cords that tangle the moment you unwind them, dry soil that means you’re hammering auxiliary rods in again and again just to get a usable reading, and the awkward conversation with a site manager about shutting down power to a server room or hospital wing — just so you can run a standard 3-pole test.

Then there’s the paperwork. Carrying a notebook in the field, scribbling down values, trying to reconstruct a compliant test record later from memory and mud-smeared handwriting. It’s slow, error-prone, and honestly unnecessary with modern equipment.

Earthing system verification is a non-negotiable part of Australian electrical compliance work. Under AS/NZS 3000 (the Wiring Rules), electrical installations must have effective earthing to protect people from electric shock and equipment from fault damage. Soil resistivity surveys are required before grounding system design on commercial and industrial builds. Periodic testing of existing installations is required for ongoing compliance, particularly in facilities covered by AS/NZS 3017. The stakes are real — and your test instrument needs to be up to the job every single time.

The HIOKI FT6041 Earth Tester was engineered to address every one of these pain points directly.

Six Measurement Methods. One Instrument.

Most earth testers on the market do the basics — 3-pole testing, maybe a 2-pole continuity check. The FT6041 goes considerably further, covering the full range of measurement scenarios encountered in real Australian electrical work:

3-Pole Method — The standard fall-of-potential method for precisely measuring ground resistance. Delivers results in just 6 seconds, with accuracy of ±1.5% rdg. ±4 dgt. across the core measurement range. Suitable for general electrical installation testing and compliance verification.

4-Pole Method (Wenner’s Method) — Essential for soil resistivity measurement prior to grounding system design on new construction projects. Geological conditions vary dramatically across Australian regions — sandy coastal soils behave very differently to dense clay or rock formations inland. Getting this right upfront saves time, money, and compliance headaches later.

MEC (Measuring Earth with a Clamp) — HIOKI’s standout capability. The MEC function — Measuring Earth with a Clamp — augments the 3-pole method with a clamp sensor to measure only the current flowing through the specific electrode under test. The result: you can measure earth resistance on live systems without disconnecting a single wire and without shutting down power. For data centres, hospitals, manufacturing facilities, and any other site where power interruption isn’t an option, this is a genuine game-changer.

3-Pole Method with 4-Terminal Measurement — When you’re dealing with very low resistance ground systems — sub-ohm values on bonded structural steel or reinforced concrete installations — this method delivers the precision required.

2-Clamp Method — For multi-point earthing systems where multiple parallel grounds are installed, the 2-clamp method lets you test individual earth electrodes in a network without disconnecting them from the system.

Low-Resistance Measurement — A built-in continuity check function using 4-terminal or 2-terminal measurement, covering ranges from 0.00 Ω to 3000 Ω. Ideal for confirming continuity of bonding conductors immediately after completing ground resistance testing — keeping your workflow tight.

Built to Survive Australian Jobsites

Anyone who’s used an entry-level earth tester in the field knows the anxiety of a $400 instrument sitting in the dirt on a wet construction site or getting covered in red dust on a regional job. The FT6041 is built like it expects to be treated badly.

IP67 Rated for Dust and Water — Completely sealed against dust ingress and protected against immersion in water to 1 metre depth. Mud splatter, rain, puddles — wash it off with water when you’re done. The EN60529-certified IP67 rating covers both the main unit and its sealed connectors.

-25°C to +65°C Operating Range — Australian conditions are extreme in both directions. Whether you’re working through a Queensland summer on an exposed substation site or doing winter commissioning work in alpine Victoria, the FT6041 keeps operating without complaint across its full temperature range.

1-Metre Drop Resistance — With the protector fitted, the FT6041 withstands a 1-metre drop onto concrete. This isn’t a marketing claim — it’s tested to the standard. For an instrument regularly carried up ladders, across scaffolding, and in and out of site vehicles, this matters.

30 V RMS Ground Potential Tolerance — In environments where stray ground potentials are present — near power distribution infrastructure, industrial plant, or high-voltage installations — the FT6041 continues to deliver stable readings with an allowable ground potential of 30.0 V RMS. Live wire warning activates automatically when ground potential is detected.

Designed to Cut Time on Site

Every minute saved on a measurement job is money back in your pocket. The FT6041 has been purpose-designed to eliminate the time-wasters.

Cord Winding That Actually Works — The measurement cables (included 25m yellow, 25m blue, and 50m red cables) are fitted with winders that retract cleanly without tangling or twisting. This sounds like a small thing until you’ve spent 10 minutes straightening knotted cables in a muddy paddock.

100 kΩ Maximum Allowable Electrode Resistance — In dry or rocky Australian soils, getting good auxiliary electrode contact is a persistent challenge. The FT6041’s 100 kΩ maximum allowable resistance for auxiliary grounding electrodes means a single insertion is usually sufficient — no repeated pouring of water around the rods, no repeat insertions trying to hit a usable resistance value.

Earth Nets Module for Concrete Surfaces — Not every measurement location has accessible soil. The included L9846 Earth Nets Module provides a flat-surface electrode alternative for hard-standing concrete areas. Open the module, make contact with the surface, add a splash of water, and take the reading. No drilling required.

6-Second Measurement Time — Full 3-pole measurement in 6 seconds. Combined with auto-hold to capture the reading and continuous measurement mode for monitoring, the FT6041 keeps your workflow moving.

Wireless Data Capture and Reporting

The FT6041 supports the optional HIOKI Z3210 Wireless Adapter (available separately or as part of the FT6041-90 and FT6041-92 KIT variants), enabling Bluetooth connectivity to iOS and Android devices.

Paired with the free GENNECT Cross app, the system allows you to:

• Automatically capture readings when auto-hold activates — no manual transcription
• Attach site photos and handwritten annotations to measurement records
• Overlay measurement values directly on site photographs and drawings
• Export completed reports to Excel for inclusion in compliance documentation packages

For electrical contractors managing compliance documentation under Australian workplace health and safety requirements, this is a significant time-saver and substantially reduces the risk of transcription errors.

Available Model Variants

For most Australian electrical contractors who need the MEC function for live-system testing, the FT6041-91 or FT6041-92 KIT is the recommended configuration.

Query: What is the HIOKI FT6041 used for?

Answer: The HIOKI FT6041 is a professional earth resistance tester used for verifying the safety and compliance of grounding systems in electrical installations. It supports six measurement methods: standard 3-pole ground resistance testing, 4-pole soil resistivity measurement, MEC clamp-on live-system measurement (without disconnecting electrodes), 4-terminal low-value resistance measurement, 2-clamp multi-electrode testing, and low-resistance continuity checks. It is widely used by electrical contractors, facility maintenance teams, and commissioning engineers for compliance work under Australian electrical standards.

Query: Can you test earth resistance without disconnecting the ground wire?

Answer: Yes. The HIOKI FT6041’s MEC (Measuring Earth with a Clamp) function allows earth resistance measurement on live systems without disconnecting any grounding electrodes. A clamp sensor detects only the current flowing through the specific electrode under test, isolating it from other parallel grounds. This capability is essential for testing in facilities such as hospitals, data centres, and industrial plants where power interruption is not possible. The optional FT9847 and CT9848 clamp sensors (included in FT6041-91 and FT6041-92 KIT) are required.

Query: What IP rating does the HIOKI FT6041 have?

Answer: The HIOKI FT6041 Earth Tester carries an IP67 rating to EN60529. This means it is completely protected against dust ingress and can withstand immersion in water to 1 metre depth. It is also rated for operation across a temperature range of -25°C to +65°C and withstands a 1-metre drop onto concrete when the protector is attached — making it suitable for demanding outdoor and construction site use.

Query: What is the difference between the FT6041 and FT6041-91?

Answer: The standard FT6041 includes the main instrument plus a full set of measurement cables, auxiliary earthing rods, the L9846 Earth Nets Module, carrying cases, and batteries. The FT6041-91 includes everything in the standard kit plus the FT9847 Signal Induction Clamp and CT9848 Clamp-On Sensor, which are required to use the MEC (live-system clamp) and 2-clamp measurement functions. The FT6041-92 KIT adds the Z3210 Wireless Adapter to the FT6041-91 configuration for Bluetooth data transfer.

Query: How do you measure soil resistivity with the HIOKI FT6041?

Answer: The HIOKI FT6041 measures soil resistivity using Wenner’s 4-pole method. Four auxiliary electrodes are inserted into the ground at equal spacing, and the instrument injects a test current between the outer two electrodes while measuring the voltage across the inner two. The instrument calculates soil resistivity from these values. This measurement is used during the design phase of grounding systems to determine the electrode configuration required to achieve the target earth resistance, accounting for the specific geological conditions at the site.

The Data Your Solar Report Actually Needs

When an inspector, asset manager, or client asks why a solar system isn’t hitting its energy yield predictions, the first question is always: what were the conditions at the time of testing? Without a calibrated irradiance measurement taken at the panel surface, any performance comparison against the manufacturer’s STC datasheet is essentially guesswork.

For solar professionals working under AS/NZS 5033 compliance obligations and the requirements of the IEC 62446-1 photovoltaic system documentation standard, having a dedicated, calibrated irradiance meter isn’t optional — it’s a core part of the commissioning and maintenance toolkit.

Four Critical Measurements. One Instrument.

The FLIR PV78 is a purpose-designed solar site measurement tool that consolidates four measurements that previously required separate instruments or cumbersome setups:

Solar Irradiance (W/m²) The PV78 measures irradiance from 0 to 1,400 W/m² — the full range you’d encounter from overcast Melbourne mornings through to peak summer radiation on a north-facing Perth rooftop. The 50–1,400 W/m² measurement range aligns with IEC 62446-1 requirements for solar PV system performance verification, making results directly usable in compliance documentation.

Panel Surface Temperature Connect the included external temperature probe and mount it directly to the panel surface for continuous module temperature readings across a range of −30 °C to 100 °C. Module temperature is essential for accurate STC correction — a panel at 65 °C will deliver measurably less power than at 25 °C, and documenting that temperature gives your performance calculations credibility.

Ambient Temperature The built-in meter sensor captures ambient temperature from −10 °C to 50 °C, logged alongside irradiance for contextual reporting — particularly useful when comparing against manufacturer performance guarantees or modelling seasonal yield variation.

Tilt Angle and Compass Direction The integrated tilt sensor and compass let you verify and document the physical orientation of panels and arrays. For new installations, this confirms panels have been mounted at the specified pitch and azimuth. For performance investigations, it helps rule out suboptimal positioning as a contributing factor to underperformance. A quick check during commissioning can prevent the kind of dispute that arises months later when an owner questions why their north-facing system is underperforming.

METERLiNK — From Rooftop to Report Without the Clipboard

One of the most practical features for busy solar teams is the FLIR METERLiNK® Bluetooth connectivity. Rather than squinting at a screen, manually transcribing values, and entering data back at the office, the PV78 transmits live readings wirelessly to the METERLiNK mobile app on your Android or iOS device.

From the app, you can monitor multiple compatible FLIR meters simultaneously, log readings with timestamps, annotate with site notes, and generate reports directly from the field. Share results with a client or upload to a job management system before you’ve even packed your test kit. For compliance-focused work, the digital audit trail is an added benefit over handwritten site notes.

The METERLiNK app also integrates with compatible FLIR thermal cameras, allowing irradiance and temperature data to be embedded directly into thermal inspection images — a significant workflow improvement for thermographers conducting PV array inspections.

Built for Australian Solar Conditions

The PV78 was designed to be positioned on or near the panel surface for continuous monitoring, not just a quick spot reading. The external probe and mounting bracket enable it to be secured in place during extended testing sessions — useful for monitoring irradiance variation during partial cloud cover, or for logging conditions over a test period to build a more representative performance picture.

The high-contrast, large LCD remains visible in direct sunlight — critical for working on rooftops in Australian summer conditions where display washout is a real usability problem with cheaper instruments.

Who Uses the FLIR PV78?

CEC-accredited solar installers use the PV78 during commissioning to capture the irradiance and temperature conditions at the time of performance testing — providing the contextual data required for IEC 62446-1 documentation and demonstrating diligence under AS/NZS 5033 requirements.

Solar O&M teams use it during scheduled maintenance visits and performance investigations, logging irradiance alongside system output data to calculate performance ratio and identify degradation or shading losses.

Solar surveyors and designers use it during pre-installation site surveys to document available solar resource and verify optimal panel orientation before system design is finalised.

Large-scale solar farm operators use the PV78 alongside dataloggers and monitoring systems to cross-reference on-ground irradiance against pyranometer data for yield analysis and performance modelling validation.
