Power quality faults in industrial and commercial facilities rarely announce themselves cleanly. A VSD tripping at midnight, flickering lighting in a production area, neutral conductors running hot, or energy bills that simply don’t match the load profile — these problems eat at uptime, compliance budgets, and operational efficiency. And they share a common frustration: getting accurate, defensible data from the source.

For maintenance engineers and electrical contractors working on substations, large distribution boards, main switchgear, or multi-cable bus systems, the physical connection challenge alone kills productivity. Standard rigid split-core CTs max out well below the conductor diameters found on high-current feeders. You end up making compromises — partial measurements, workarounds, or a second site visit with different equipment — none of which are billable, and all of which erode confidence in the final report.

The Megger MPQ2000 Platinum Plus Kit is built to eliminate those compromises entirely.

The Solution: A Complete, Large-Format Power Quality Investigation Kit

The MPQ2000 Platinum Plus Kit centres on the MPQ2000 analyser — Megger’s flagship portable 3-phase power quality instrument — and adds four MCCV6000-37 flexible rope current transformers with a 37 cm internal diameter. That’s the widest flexible CT option in the MPQ2000 accessory range, capable of wrapping around large conductors, bundled cables, bus bars, or even multiple conductors in a single measurement pass.

The kit ships ready for immediate deployment with voltage leads, a 32 GB SD card, USB and Ethernet communication cables, universal power cords, fused adapters, and a soft-sided carry bag. It’s the one kit that removes every physical limitation between your analyser and the circuit under test.

IEC 61000-4-30 Class A: The Measurement Standard That Matters

When a power quality report is destined for a utility, a client, or a regulatory body, measurement methodology matters as much as the result itself. The MPQ2000 is fully IEC 61000-4-30 Edition 3 Class A compliant across all parameters — not just a subset. That means voltage sags and swells, THD, harmonics, inter-harmonics, flicker, unbalance, frequency, RVC, and transient detection all meet the highest tier of the standard.

For Australian electrical contractors and facility managers operating under AS/NZS 61000 guidelines and utility network codes, Class A compliance means your data will stand up to scrutiny. There’s no need to defend measurement methodology or re-collect data with a higher-grade instrument — the MPQ2000 is already the highest grade available.

Four MCCV6000-37 Flexible CTs: Maximum Reach, Zero Guesswork

Each MCCV6000-37 flexible rope CT in this kit offers four selectable current ranges — 60 A, 600 A, 3,000 A, and 6,000 A — all self-identifying. The moment you plug a CT into the MPQ2000, the analyser automatically recognises which clamp it is and configures the correct measurement range. There’s no manual range entry, no risk of a misconfigured channel invalidating a multi-day recording, and no wasted recordings from operator error.

The 37 cm internal diameter handles conductors and cable groups that are simply out of reach for conventional rigid CTs. Bus ducts, large service entry cables, parallel feeder bundles — these are the measurement points that typically require either an outage for sensor installation or an expensive specialised solution. With the MCCV6000-37, you clamp around the conductor with no disconnection required, and the rain-tight construction means you can leave it in place for extended outdoor or sub-floor recording campaigns.

Powering the CTs directly from the MPQ2000 eliminates additional batteries and simplifies your setup. One power source, four clamps, one record button.

Record Verification: Confidence Before You Leave the Site

One of the most costly mistakes in power quality investigation is returning to the office only to find the data is invalid — a CT on the wrong phase, a voltage lead reversed, a range mismatch. The MPQ2000’s connection verification function checks the unit’s configuration before recording begins and flags any issues on screen. Combined with automatic CT recognition, this creates a double-check system that catches setup errors while you’re still on site and able to fix them.

The MPQ2000 also supports on-board data analysis. Rather than packing up and waiting until you’re back at your desk, you can review recorded waveforms, check event summaries, and compare against customisable templates directly on the instrument’s backlit colour VGA display. For time-pressured field engineers, being able to confirm a fault has been captured — or rule it out and move to the next test point — without unpacking a laptop is a genuine productivity gain.

Measurement Depth: Everything from Transients to Long-Term Energy Trends

The MPQ2000 measures across the full spectrum of power quality phenomena relevant to Australian industrial and commercial installations:

• Voltage and current: AC RMS up to 1,000 V and DC up to ±1,500 V across 4 voltage channels and 5 current channels simultaneously. AC and DC measurement requires no common neutral, which simplifies connections on systems where neutral access is restricted.
• Harmonics and inter-harmonics: Continuous measurement from 0 to 50th order, with waveform analysis extending to the 128th order through the included PC software. Essential for identifying the true source of harmonic distortion on sites with variable speed drives, UPS systems, switch-mode power supplies, and large LED lighting installations.
• IEC flicker: Pst over 10 minutes and Plt over 2 hours, both measured per IEC 61000-4-15. Relevant for facilities operating arc furnaces, large welders, or any load with rapid, cyclic variation — and increasingly important for solar inverter compliance assessments under AS/NZS 4777.
• Voltage unbalance: Both IEC and ANSI methodologies per IEC 61000-4-27. For facilities with 415 V three-phase distribution supplying motors, unbalance is a leading cause of premature motor failure and should be documented in any maintenance baseline.
• Transient detection: Down to 1 microsecond, triggered off voltage channels with up to 9 pre-trigger and 3,600 post-trigger cycles captured. Captures the fast-rise switching transients that damage sensitive electronics and are typically invisible to slower-sampling instruments.
• Motor inrush: Records RMS, power, energy, and power factor every cycle simultaneously. Captures up to one minute of raw waveform data on every motor start-up. Supports both three-phase and single-phase motor monitoring over weeks or months without manual intervention.
• Energy parameters: KWH, KVARH, and KVAH per IEEE 1459, with aggregation windows from 1 cycle to 1 hour. Supports billing verification and load studies without additional metering equipment.

Communication and Data Transfer: No Bottlenecks

Recorded data transfers via USB cable, USB stick, Ethernet, or directly from the SD card — no proprietary hardware required, no licence dongles. The included 32 GB SD card handles extended recording campaigns, and expanding capacity is as straightforward as swapping to a larger card.

The included Megger PQ Power Quality Analysis software — provided at no additional cost and with no licence fees — unlocks advanced charting, waveform analysis to the 128th harmonic order, and automated report generation. Its configuration wizard handles instrument setup from the PC, while scheduled recording and automatic configuration allow unattended deployment across multiple sites.

For network integration, the MPQ2000 supports Ethernet communications and wireless operation via an off-the-shelf bridge. The optional external Ethernet port lid modification (MPQ2000EE) allows network connection while the case remains closed and sealed.

Built for the Australian Field Environment

The IP54 weatherproof enclosure with padlock provision means the MPQ2000 can be left recording in switchrooms, plant rooms, outdoor substations, and rooftop installations without concern for dust ingress or water splash. The NiMH battery pack delivers eight hours of standalone operation — enough for a full shift — and recharges in three hours. Operating temperature range of -20°C to +50°C covers every realistic Australian deployment environment.

Safety ratings of CAT IV at 600 V and CAT III at 1,000 V (at altitude below 2,000 m) ensure the instrument is appropriately rated for connection at the main distribution level — exactly where large-conductor power quality measurements are most frequently required.

APPLICATION USE CASES

1. Main Switchboard and Substation Investigation — Industrial Facilities

When a manufacturing client reports unexplained process interruptions, motor failures, or high electricity costs without an obvious cause, the starting point is a comprehensive baseline measurement at the main switchboard or utility metering point. The MPQ2000’s 1,000 V AC range covers most LV distribution entry points, while the MCCV6000-37 flexible CTs handle the large-diameter service entry cables without any disconnection. Class A measurements over a representative recording period — typically one to two weeks — capture sag/swell events, harmonic levels, unbalance, and energy demand data that forms the basis of a defensible power quality audit report.

2. Variable Speed Drive (VSD) and Harmonic Assessment

Australian industrial sites running large VSD populations are increasingly subject to harmonic distortion limits under AS/NZS 61000.3.6 and utility network connection agreements. The MPQ2000 measures harmonics and inter-harmonics continuously from the 0th to 50th order during recording, while the included PC software extends analysis to the 128th order for forensic assessment. Harmonic direction measurement identifies whether distortion is being injected from site loads or entering from the utility — a critical distinction when fault responsibility is in dispute. Transformer de-rating calculations, capacitor bank resonance assessment, and filter sizing studies are all supported by the dataset the MPQ2000 generates.

3. Solar PV and Battery Storage Commissioning and Compliance (CEC / AS/NZS 4777)

Grid-connected solar inverters in Australia must comply with AS/NZS 4777.2, which includes limits on harmonic injection, voltage unbalance contribution, and flicker. The MPQ2000’s 1,500 Vdc measurement capability allows direct DC bus monitoring on string inverters alongside AC output measurement — capturing both sides of the energy conversion in a single recording session. IEC flicker measurement per IEC 61000-4-15, combined with harmonic and voltage unbalance data, provides the evidence set required by network service providers for embedded generation connection assessments. The 37 cm CTs handle the large AC output conductors typical of commercial and industrial-scale PV systems.

4. Motor Starting, Inrush, and Load Monitoring — Long-Term Campaigns

Industrial maintenance teams tracking motor health and drive system performance benefit from the MPQ2000’s dedicated motor inrush mode, which captures RMS, power, energy, and power factor every cycle and records up to one minute of raw waveform data on each motor start event. The instrument can monitor a single motor or a group of motors continuously for weeks or months, providing data for predictive maintenance planning, insurance assessments, and efficiency baselining. The IP54 enclosure and field-replaceable battery support unattended installation in plant room environments without concern for accidental shutdown.

5. Flicker and Lighting Quality Investigations — Commercial Buildings and Hospitals

Occupant complaints about flickering, surging, or strobing lighting are increasingly common as LED driver quality varies widely across projects. The MPQ2000 measures IEC flicker (Pst and Plt) per IEC 61000-4-15, rapid voltage change events, and voltage sags/swells that directly cause visible flicker symptoms. For facilities managers and consulting engineers investigating complaints under AS/NZS 1680 compliance frameworks or health and safety obligations — particularly in healthcare, education, and manufacturing environments — this measurement set provides objective evidence of the root cause and supports lighting system rectification scoping.

6. Capacitor Bank and Power Factor Correction Assessment

Facilities with existing power factor correction equipment need periodic assessment to confirm capacitors are performing to specification and not creating resonance issues with site harmonics. The MPQ2000 logs real, reactive, and apparent power (KW, KVAR, KVA), displacement and true power factor continuously across all recording intervals. Comparing pre- and post-capacitor switching measurements confirms correction effectiveness, while harmonic analysis identifies whether parallel resonance between capacitor banks and transformer impedance is amplifying harmonic distortion — a common source of unexplained equipment failures on sites with both VSD loads and PFC equipment.

7. Utility Billing Verification and Demand Management

Energy managers and facilities teams with reason to question utility billing accuracy can use the MPQ2000 to conduct independent metering verification. Energy parameters — KWH, KVARH, and KVAH — are measured per IEEE 1459 across aggregation windows from 1 cycle to 1 hour. Simultaneous recording of demand profile, power factor, and harmonic distortion levels provides the context needed to validate network tariff classifications, assess demand reduction opportunities, and prepare supporting data for retailer or network operator disputes.

---

What size conductors can the MCCV6000-37 flexible CT measure?

The MCCV6000-37 flexible rope current transformer has a 37 cm internal diameter, allowing it to clamp around large-diameter conductors, cable bundles, and bus bars that are inaccessible to standard split-core CTs. It supports four current ranges — 60 A, 600 A, 3,000 A, and 6,000 A — all automatically identified by the MPQ2000 analyser when connected. The CT is rain-tight and powered directly from the MPQ2000, requiring no separate battery or power source.

---

What power quality parameters does the Megger MPQ2000 measure?

The MPQ2000 measures a comprehensive set of power quality parameters including: AC and DC voltage and current (RMS), voltage and current sags, dips, and swells, transients down to 1 microsecond, harmonics and inter-harmonics from 0 to 50th order continuously (128th order in software), total harmonic distortion (THD), total demand distortion (TDD), IEC flicker (Pst and Plt), IEC and ANSI voltage unbalance, frequency, rapid voltage change, phase angle stability, active/reactive/apparent power (KW, KVAR, KVA), displacement and true power factor, and energy parameters (KWH, KVARH, KVAH). All measurements comply with the relevant IEC standards under IEC 61000-4-30 Class A.

---

Can the Megger MPQ2000 be used for solar PV compliance testing in Australia?

Yes. The MPQ2000 is well-suited to solar PV compliance testing under the Australian AS/NZS 4777.2 standard. It measures DC voltage up to ±1,500 Vdc for PV string monitoring, IEC flicker per IEC 61000-4-15 for inverter flicker assessment, harmonics and inter-harmonics per IEC 61000-4-7, and voltage unbalance per IEC 61000-4-27 — all parameters required for network service provider embedded generation connection assessments. AC and DC measurements can be taken simultaneously with no common neutral required.

---

How does the MPQ2000 record verification feature work?

Before the MPQ2000 begins recording, its connection verification function checks the entire instrument configuration — CT identification, current range, voltage lead connections, and phase assignment — and displays any detected setup errors on screen. Combined with automatic CT recognition (which configures the correct current range as soon as a self-identifying CT is plugged in), this creates a two-layer safeguard against the misconfiguration errors that commonly invalidate multi-day power quality recordings. You receive confirmation of a valid configuration before committing to a recording session.
