Two things have happened to power electronics test benches over the last few years, and neither of them has been kind to the equipment already sitting in the rack.

The first is voltage. EV platforms have moved to 800 V architectures. Utility-scale PV strings and battery energy storage systems routinely sit at 1500 V DC and climb from there. Most precision power analysers on the market top out at 1000 V direct input, which means the moment your DC bus exceeds that, you’re bolting an external voltage divider onto the front of the instrument. That divider brings its own amplitude error, its own phase shift, its own temperature coefficient — and every one of those errors stacks on top of the analyser’s own uncertainty. You end up quoting an efficiency figure to three decimal places that your measurement chain can’t actually support.

The second is channel count. A dual-inverter e-Axle needs DC bus, two three-phase AC outputs, and mechanical power from two motors — measured simultaneously, on the same time base. A multi-string PCS needs a measurement point per string plus the grid side. Meanwhile the rack itself hasn’t grown. Every rack unit an instrument occupies is a rack unit unavailable to the power supply, the load bank, or the ScopeCorder.

The Yokogawa WT1500 Precision Power Analyzer was designed around both problems at once.

What the WT1500 actually does differently

Released in August 2026, the WT1500 is the newest member of the WT series and the first to offer 2000 V direct input. It sits in a 2U (approximately 88 mm) JIS/EIA rack-mount chassis, and inside that chassis you can fit up to four power measurement elements and up to four motor evaluation channels.

The headline number is ±0.038% total power accuracy at DC and at 50/60 Hz. That figure is the sum of the two accuracy terms Yokogawa specifies: ±0.018% of reading plus ±0.02% of range. Read that way it tells you something useful — the range term dominates when your signal sits low in the range, so range selection still matters, but at or near full range you’re working with a genuinely reference-class instrument. For context, within Yokogawa’s own line-up the WT1500 is specified tighter at DC than both the WT5000 (±0.07%) and the WT1800R (±0.1%).

Low power factor performance is where efficiency measurements usually fall apart, and the WT1500 holds ±0.07% of apparent power at 50/60 Hz with a power factor of zero. That’s the specification that governs no-load inverter testing and standby loss measurement, where the active power component is a small fraction of the apparent power flowing.

Choose your elements: high voltage or wide bandwidth

The WT1500 doesn’t force a single compromise on you. Each input element is specified at order time as one of two types, and you can mix them freely within one chassis.

HV (High Voltage) elements take direct measurements up to 2000 V, with voltage ranges of 6 / 15 / 30 / 60 / 150 / 300 / 600 / 1000 / 2000 V at crest factor 3. Frequency band runs DC to 300 kHz typical. This is the element for battery packs, DC links, PV strings and ESS DC buses.

WB (Wide Bandwidth) elements cover ranges to 1000 V with a DC to 2 MHz typical frequency band. This is the element for SiC and GaN converter work, fast-switching inverter stages, and anywhere the harmonic content of the switching waveform genuinely matters to your loss budget.

A typical PCS evaluation configuration might be three WB elements and one HV element — three-phase AC on the wideband inputs, high-voltage DC on the HV input, in a single 2U box. That combination is ordered as a WT1504-10-WB3-HV1.

Both element types share the same acquisition front end: 16-bit resolution, 2.5 MS/s sample rate, with voltage and current converted simultaneously so there’s no inter-channel skew to correct for.

Built for the rack, not the bench

Where the WT1500 separates itself from general-purpose power analysers is in how it expects to be operated — which is to say, mostly not by hand.

The front panel carries a small 2.9-inch monochrome LCD and a handful of control keys. That’s deliberate. Real operation happens through the built-in web server (browser-based control and monitoring over Ethernet), through the free WTViewerEfree PC software, or through direct communication commands over Ethernet or USB. If you do want a local display, a USB-C port drives an external monitor at 1280 × 720, and connecting a touchscreen gives you full touch control of the menus.

For data out, the instrument speaks the languages an automated test system actually uses:

• CAN / CAN FD (the /CN1 option) streams measurement data straight onto the vehicle bus at each update interval — up to 512 items depending on bit rate — for direct integration with ECU and control systems.
• Low-latency UDP provides continuous real-time measurement data for closed-loop control and fast anomaly detection.
• Modbus/TCP server suits long-duration monitoring on industrial pump and fan rigs.
• IEEE 1588 (PTP v2) time synchronisation timestamps WT1500 data against compatible instruments — including the SL2000 ScopeCorder — to roughly ±10 µs, so power values and captured waveforms line up on one timeline.
• Standard Ethernet services include VXI-11, Socket, HiSLIP, FTP and web server over 1000BASE-T.

Auto-setup functions handle production-line signal variation without an operator standing over the instrument: 10 ms data updates, automatic frequency tracking, adaptive filtering, and measurement down to 0.1 Hz.

Twenty channels when four isn’t enough

When one chassis runs out of inputs, the /SY1 multi-unit synchronisation option links up to four sub-units to a main unit over optical fibre (SFP transceivers, up to 300 m). That gives you 20 power channels and 20 motor channels in one synchronised system, with ±400 ns synchronisation accuracy between units.

Critically, it behaves as one instrument. The main unit configures ranges, filters, scaling and wiring on every sub-unit, collects all normal and harmonic measurement values plus compressed waveform data, and saves the whole system’s setup in a single file. Data from sub-units feeds directly into the main unit’s efficiency calculations and user-defined computations.

Please note: Yokogawa has stated the /SY1 option will be released later, and can be added to a purchased unit via an option upgrade licence. If multi-unit synchronisation is on your critical path, talk to us about current availability before you commit to a delivery date.

Motor evaluation — encoder and resolver, mixed freely

Five motor evaluation options are available, and you select one at order time:

The instrument computes rotating speed, torque, synchronous speed, slip and motor output alongside the electrical measurements. Resolver channels carry a 1 MHz typical bandwidth on the carrier, sine and cosine inputs, with electrical angle measurement error of ±0.1° typical and a maximum display of 150,000 rpm. Built-in Ld/Lq calculations support vector analysis of permanent magnet synchronous motors.

Because encoder and resolver channels can be mixed in one instrument, a test cell running two different motor types doesn’t need two different analysers.

Where it earns its keep

Power conditioning systems and energy storage. Multi-string PCS architectures above 1500 V need many measurement points at high accuracy. The 2000 V HV element removes the external divider from the chain, and multi-unit synchronisation scales the channel count to match the string count.

Data centre and EV fast-charger power supplies. AC/DC conversion efficiency measured input-to-output in a single unit, with the WT1500 holding specification across 1% to 130% of range — which matters when the load is dynamic rather than steady-state.

EV powertrain and e-Axle efficiency. Simultaneous DC, three-phase AC, torque and speed acquisition across multiple power paths, with results streamed onto CAN FD for the control system.

Industrial motor duration testing. Long-term watt-hour and ampere-hour integration on inverter-driven pumps and fans, monitored over Modbus/TCP.

Ordering the WT1500 — and the part people get wrong

The WT1500 is a configured instrument, not a shelf item, and the model code carries real consequences. You select the number of elements (WT1501-10 through WT1504-10), the HV/WB split within those elements, the installation type (-BN benchtop, -RE EIA rack, -RJ JIS rack), menu language, power cord, and then the additional options: /M1 32 GB memory, one motor evaluation option, /SY1, and /CN1.

The single most important thing to understand before you order: the WT1500 has no direct current input. All current measurement is made through a Yokogawa current sensor or clamp probe, and those are sold separately. The instrument provides sensor power and supports automatic sensor recognition with ratio and phase compensation for compatible models, but the sensor itself is a separate line on the order. Sensor options run from the CT60 (60 A peak, DC to 800 kHz) through the CT1000A and CT1000S split-core (1000 A) to the CT2000A (2000 A RMS), plus AC clamp probes. Getting this wrong is the difference between an instrument that works on day one and one that sits in its box.

For Australian sites, specify the -R (AS Standard) power cord. And if you’re measuring above 1000 V on an HV element, you’ll need the 758932 high-voltage safety terminal adapter set together with appropriately rated cable.

“Due to the nature of this product, it is possible to touch its metal parts. There is a risk of electric shock – use this product with caution.”

“Before operating the product, read the user’s manual thoroughly for proper and safe operation.”

Do not use the WT1500 for measurements in Measurement Category IV.

What is the Yokogawa WT1500? The Yokogawa WT1500 is a precision power analyser released in August 2026 as the newest member of Yokogawa’s WT series. It measures up to four power channels and four motor channels in a 2U rack-mount chassis, with ±0.038% power accuracy at DC and 50/60 Hz and the series’ first 2000 V direct voltage input.

How accurate is the WT1500 power analyser? The WT1500 is specified at ±(0.018% of reading + 0.02% of range) for active power at both DC and 50/60 Hz — a total of ±0.038%. At 50/60 Hz with a power factor of zero, accuracy is ±0.07% of apparent power. Current sensor accuracy is added on top of these figures.

Can the WT1500 measure 1500 V DC directly? Yes. Fitted with an HV (High Voltage) element, the WT1500 measures up to 2000 V directly, with a dedicated 2000 V range. It is rated 1500 V DC CAT II on the HV voltage input terminals. For measurements above 1000 V, Yokogawa requires the 758932 high-voltage safety terminal adapter set and appropriately rated cable.

What is the difference between the HV and WB elements? HV (High Voltage) elements measure up to 2000 V with a DC to 300 kHz typical bandwidth. WB (Wide Bandwidth) elements measure up to 1000 V with a DC to 2 MHz typical bandwidth. Both types can be mixed within a single WT1500 chassis — for example, three WB elements plus one HV element for a PCS evaluation.

Does the WT1500 have a direct current input? No. All current measurement on the WT1500 is made through an external Yokogawa current sensor or clamp probe, which is sold separately. The instrument supplies sensor power and automatically recognises compatible sensors, applying the correct ratio and phase compensation.

How many channels can a WT1500 system measure? A single WT1500 chassis supports up to four power channels and four motor channels. With the /SY1 multi-unit synchronisation option, one main unit and up to four sub-units connected over optical fibre form a single 20-power-channel, 20-motor-channel system with ±400 ns synchronisation accuracy.

How does the WT1500 compare to the WT5000 and WT1800R? The WT5000 offers the most elements (7) and the WT1800R six, but the WT1500 is specified tighter for DC power accuracy at ±0.038%, against ±0.07% for the WT5000 and ±0.1% for the WT1800R. The WT1500 is also the only one of the three with 2000 V direct input, and it fits four channels into 2U. The WT5000 and WT1800R offer direct current input; the WT1500 requires external current sensors.

Which motor evaluation option should I choose? Choose /EM1 for up to two encoder-based motors, /RM1 for one resolver-based motor, /EM2 for up to four encoder motors, /RM2 for up to two resolver motors, or /EM1RM1 to mix two encoder motors with one resolver motor. Only one motor evaluation option can be fitted per instrument, and it is selected at order time.

Is the WT1500 suitable for use in Australia? Yes. The WT1500 accepts 220–240 VAC at 50 Hz and is ordered with the -R (AS Standard) power cord option for Australian sites. Yokogawa’s specifications cite the EMC Regulatory Arrangement in Australia and New Zealand, EN 61326-1 Class A Group 1. As a Class A instrument it is intended for industrial environments.

What does the WT1500 model code mean? The model number gives the element count (WT1501-10 = one element, through WT1504-10 = four). The first suffix gives the element mix, e.g. -WB3-HV1 means three wideband and one high-voltage element. Then comes installation type (-BN benchtop, -RE EIA rack, -RJ JIS rack), menu language (-HE, -HC, -HG), power cord (-R for Australia), and finally additional options such as /M1, /EM2, /SY1 and /CN1.

There’s a specific and expensive mistake that gets made on three-phase measurement: using a two-element meter on a four-wire system.

On a balanced load you might not notice. The numbers look plausible. But the moment the load is unbalanced — and in a real building, a real factory, a real solar installation, it always is — the two-wattmeter method stops giving you correct total power on a four-wire circuit. Current is returning through the neutral, and a two-element instrument has no channel measuring it.

The Yokogawa WT333E digital power meter is the three-element answer. Three voltage inputs, three current inputs, one per phase, with total power calculated as the straightforward sum: P∑ = P1 + P2 + P3.

That’s not a clever algorithm. It’s just having enough channels — and on a four-wire system, three is the number.

Four wiring configurations, one instrument

The WT333E is the most configurable model in the WT300E series, supporting:

Three-phase four-wire (3P4W). The configuration that matters most in Australia. Our distribution standard is 400 V (nominally 415 V) phase-to-phase with a 230 V phase-to-neutral relationship — a four-wire system by design. Every commercial switchboard-fed load, every mixed single-phase-and-three-phase installation, every unbalanced building distribution is 3P4W. Total voltage, current and power are summed across all three elements, giving correct results regardless of balance.

Three-voltage three-current (3V3A). The three-wattmeter method applied to a three-wire system. You don’t strictly need three elements on a three-wire circuit, but 3V3A gives you something two elements can’t: individual voltage, current and power data for each phase, plus improved handling of distorted and unbalanced conditions. Total apparent power is computed as (√3/3)(S1 + S2 + S3).

Three-phase three-wire (3P3W). The conventional two-wattmeter method, if you want it.

Single-phase three-wire (1P3W). Split-phase measurement.

The practical upshot: one instrument on the shelf covers every wiring configuration you’re likely to encounter, and you don’t have to make a purchasing decision about your future measurement problems today.

Per-phase visibility, which is the point

Total power tells you what the system draws. Per-phase data tells you why.

With three elements, the WT333E gives you voltage, current, active power, apparent power, reactive power, power factor and phase angle for each element independently — and frequency measurement selectable from the voltage or current of element 1, 2 or 3.

That’s what turns a power meter into a diagnostic instrument. Phase imbalance that’s overloading one conductor. A power factor problem isolated to one leg. A harmonic issue that only appears on the phase feeding the drives. None of that is visible in a summed total.

Accuracy and bandwidth

Basic power accuracy is ±(0.1% of reading + 0.05% of range) at 45–66 Hz, consistent across all measurement ranges. Yokogawa states that WT332E and WT333E performance matches that of the WT310E.

The influence at power factor 0 is ±0.1% of apparent power between 45 and 66 Hz — half the previous generation’s figure. On three-phase distribution work this is the specification that decides whether your measurement is useful. Reactive-heavy loads, lightly loaded motors, capacitor banks and no-load conditions all sit at low power factor, and at low PF the influence term dominates your total uncertainty.

Bandwidth is DC and 0.1 Hz to 100 kHz, with voltage and current converted simultaneously through a 16-bit A/D at approximately 100 kS/s. Simultaneous conversion is what preserves the phase relationship between the voltage and current channels — and phase error is what destroys power accuracy on any waveform that isn’t a clean sinusoid. Which, on a modern distribution board feeding inverters, LED drivers, UPS units and variable-speed drives, is most of them.

Where the WT333E does work others can’t

Three-phase four-wire distribution measurement. Unbalanced building loads, mixed-phase installations, commercial plant. Correct total power plus per-phase diagnosis.

Unbalanced load analysis. Identifying which phase is carrying the imbalance, quantifying it, and having the per-element data to prove it.

Three-phase efficiency measurement. Efficiency computation is built into the WT333E (as it is on the WT332E, and unlike the single-element WT310E). Measure a converter, transformer, drive or motor input against its output on one instrument, one timebase, one calibration.

Motor and rotating machinery duration testing. Integration runs to 10,000 hours — approximately one year. With the /C7 Ethernet option, Modbus/TCP feeds Yokogawa’s GA10 data-gathering software, which can combine your electrical measurements with temperature, torque and rotation speed data across up to 200 channels. That’s a complete motor test dataset in one logging environment.

UPS conformance and evaluation. Input and output levels, efficiency, frequency and THD, with average active power under integration mode giving a true consumption figure for fluctuating loads.

Harmonic and power quality investigation on three-phase systems. With the /G5 option, PLL-synchronised harmonic analysis to the 50th order on all three elements, with a settable maximum THD order — so you can see harmonic content phase by phase rather than as an aggregate.

Three-phase product development and QA. USB standard, GP-IB (–C1) or RS-232 (–C2) at order, /C7 Ethernet with Modbus/TCP and VXI-11 for recorder and PLC integration, and the /DA12 option for twelve channels of ±5 V analogue output — sized for the parameter count that three elements generate.

Australian context worth knowing

The 3P4W capability is the reason this model matters here. Australian LV distribution is four-wire, and a great deal of commercial and industrial measurement work involves loads that are meaningfully unbalanced. The WT333E’s 300 V and 600 V voltage ranges cover both the 230 V phase-to-neutral and 400/415 V phase-to-phase relationships directly.

Now the important caveat, and it deserves to be blunt: the WT333E is a measurement category CAT II, 600 Vrms instrument. Yokogawa’s documentation states plainly that it is a measurement category II product and must not be used for measurement categories III or IV.

CAT III covers facility circuits — distribution boards and circuit breakers. CAT IV covers power source circuits such as entrance cables. So while the WT333E is the correct topology for four-wire systems, it is a bench, test-rig and machine-terminal instrument, not a switchboard instrument. If your job is measuring at the distribution board itself, you need an instrument rated for that category, regardless of how good this one’s specifications are. That distinction is a safety matter, not a paperwork one.

Order the –R power cord suffix for the AS-standard plug. Supply is 100–240 VAC (90–264 V permitted) at 48–63 Hz, 70 VA maximum.

The instrument is Class A under EN 55011 — an industrial-environment device. Operating it in a residential area may cause radio interference, and correcting that interference is the user’s responsibility.

Why buy the WT333E from us

The three-element decision usually comes down to one question, and it’s worth getting right before you order: does your system have a neutral that carries current? If yes, you need three elements. If no, two will do — and we’ll tell you that rather than sell you up.

We’ll also work through the option codes with you. /G5 harmonics, /C7 Ethernet, /EX1 or /EX2 external sensor input and /DA12 analogue output are factory-fitted at time of order. Getting the configuration right at purchase is considerably cheaper than discovering the gap three months into a project.

We’re a test and measurement specialist. We supply, we support, we calibrate, and we’re around after the sale. Tell us what you’re measuring and we’ll help you spec it.

TECHNICAL SPECIFICATIONS

What is the Yokogawa WT333E used for? The Yokogawa WT333E is a three-element digital power meter used to measure three-phase four-wire (3P4W), three-voltage three-current (3V3A), three-phase three-wire and single-phase three-wire systems. Three elements give correct total power on unbalanced four-wire loads plus individual voltage, current and power data for every phase — making it the model of choice for three-phase distribution measurement, motor and drive efficiency testing, UPS evaluation and phase-by-phase harmonic analysis.

Why do I need three elements instead of two? Because of the neutral. On a three-phase four-wire system, current returns through the neutral conductor, and a two-element instrument has no channel measuring it — so on an unbalanced load, a two-element meter will not give correct total power. Three elements measure each phase independently and sum them (P∑ = P1 + P2 + P3), which is correct regardless of balance. If your system genuinely has no current-carrying neutral, two elements are sufficient and the WT332E will do the job.

Can the WT333E measure 400/415 V three-phase in Australia? Its 600 V range covers 400/415 V phase-to-phase and its 300 V range covers 230 V phase-to-neutral, and the 3P4W wiring configuration matches Australian LV distribution. However, the WT333E is a measurement category CAT II, 600 Vrms instrument and Yokogawa states it must not be used for CAT III or CAT IV measurements. That makes it suitable at machine terminals and on test rigs fed from a fixed installation, but not for measurement at distribution boards, circuit breakers or service entrance cables.

What is the difference between the WT332E and WT333E? The number of input elements. The WT332E has two and supports 1P3W and 3P3W wiring. The WT333E has three and adds 3P4W and 3V3A configurations, plus per-phase data on all three phases and frequency measurement selectable from any of the three elements. Accuracy, bandwidth, current ranges, voltage ranges, physical size and options are otherwise the same.

What is 3V3A and when would I use it? Three-voltage three-current is the three-wattmeter method applied to a three-wire system. You don’t need three elements on a three-wire circuit for total power, but 3V3A gives you individual phase data that the two-wattmeter method cannot, and handles unbalanced and distorted conditions better. Use it when you want per-phase diagnostic detail on a three-wire load. Total apparent power in 3V3A is computed as (√3/3)(S1 + S2 + S3).

Does the WT333E measure harmonics on all three phases? With the /G5 harmonics option fitted, yes — harmonic measurement applies to all installed elements. It uses PLL synchronisation across a fundamental frequency range of 10 Hz to 1.2 kHz, analyses to the 50th order, and allows the maximum order used for THD calculation to be set by the user. Without /G5 the instrument measures RMS, voltage mean and DC values but not harmonic components.

Can the WT333E calculate efficiency? Yes. Efficiency computation is built into both the WT333E and the WT332E. Because both the input and output measurements are taken by the same instrument on the same timebase and the same calibration, you avoid the synchronisation and relative-drift errors that come with running two separate power meters and reconciling their logs afterwards.
