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.

Multi-channel measurement application

Motor control & inverter circuit development
Limitation of 4 channel scope
Whole-system measurement is impossible with a four channel scope; the real difficulty is measuring the timing between IGBT gate signals within the inverter.

Voltage and current measurements between 3 phases and the IO of the motor driver IC is a very challenging test with a four channel scope. The truly practical solution is an eight channel MSO.

Electronic control unite & mechatronic test
Limitation of 4 channel MSO
The additional logic inputs of a four-channel MSO mixed signal oscilloscope provides enough channels, but this method has a blind-spot. Digital waveform analysis using logic inputs alone cannot reveal anomalies such as voltage drift, noise, distortion or ringing, and measure rise-fall times. ECU testing requires stringent examination of all digital waveforms – and analogue input channels are the best tool for the job.

8 channels
The key to efficient and reliable high performance electric motors is the modern inverter design, or ‘Intelligent Power Module’. Multi-channel, highspeed waveform measurement is an absolute necessity. Four channels are simply not enough. Boasting eight true analogue inputs, the DLM5000 empowers today’s engineer with a convenient and comprehensive measurement system.

Numerous I/O analog, digital, and serial-bus waveforms surrounding the Electronic Control Unit (ECU) must be measured. The DLM5000 offers ample channel-count and architecture to monitor eight analogue channels and up to 24-bits of logic input while simultaneously performing protocol analysis such as UART, I2C, SPI, CAN, CAN FD, LIN, CXPI and FlexRay. The DLM5000 can speed up the R&D process when four channels are not enough.

YOKOGAWA DLM5000 Series Available Models

Lasers are commonly used for the detection of gases such as CO2, N2O and NO in environmental monitoring. This detection is achieved by identifying the wavelength absorption lines of the different gases. Howeve the “side modes” of the laser, which are difficult to detect, reduce the laser’s ability to distinguish between the different gases.

This Yokogawa AQ6377 Optical Spectrum Analyzer has been designed to overcome this difficulty in the wavelength range from 3.5 to 5 µm (mid-infrared). It has a wavelength resolution of 0.2 nm, a wavelength accuracy of ±0.5 nm, a dynamic range of up to 50 dB and a level sensitivity of up to -60 dBm.

Quantum cascade lasers (QCLs), used in particular for medical spectroscopy diagnostics, operate using a pulsed technique. The AQ6377 analyzer is capable of making measurements over the entire wavelength range and evaluating pulsed QCL signals with a low repetition rate.

Improvement in dynamic range and sensitivity has been achieved by reducing the influence of stray light in the monochromator. The integrated calibration light source takes advantage of the natural absorption properties of acetylene gas to provide a wavelength calibration signal at 0.6 picometer precision. This source also has automatic optical alignment to compensate for any drift in the optical axis caused by vibrations and shocks during transport, as well as drift due to temperature changes.

In addition, the free space optical input allows both single-mode and multi-mode MWIR fibers (up to 400 µm) to be connected to the same optical spectrum analyzer, and ensures low insertion loss. The absence of physical contact also avoids the risk of damage when the fibers are connected.

Spectral measurements can be strongly affected by the absorption of water vapor and carbon dioxide. The purge function of the AQ6377 is designed to significantly reduce the influence of these gases by continuously supplying pure purge gas (such as nitrogen) to the monochromator via dedicated connectors on the rear panel.

Key Features:

• Wavelength range: 1900 to 5500 nm 
• 5 wavelength resolution settings: 0.2 to 5 nm
  Enables the user to choose the best value according to the device/system under test.
• Wide measurable level range: −60 to +13 dBm
  Suitable to measure high power as well as low power sources used in different fields of application. Sensitivity: HIGH1-3 are only high dynamic mode.
• Wavelength accuracy: ±0.5 nm
  Easily maintained due to the built-in Calibration Function and wavelength reference source.
• Close-in dynamic range: 50 dB
• Horizontal scale also in Wave Number (cm−1)
  In addition to the commonly-used scales in wavelength (nm) and frequency (THz).

Purge Feature

Due to the high resolution and sensitivity of the AQ6377, it can actually detect the presence of water molecules in the air. The water vapor is detected in the upper Near-IR wavelength region and could overlap with or mask the spectral characteristics of the actual device under test in that particular region.

By continuously supplying a pure purge gas such as nitrogen to the monochromator through the ports on the back panel, the AQ6377 can reduce the influence of water vapor absorptions and provide more reliable and accurate measurements than ever before.

Built-in Cut Filter for High Order Diffracted Light

Due to the diffractive technology used, the monochromator in some circumstances could generate high order diffracted light, which appears at wavelengths equal to the integral multiple of input wavelengths.

By cutting incoming light below 1500 nm with the built-in filter, the AQ6377 drastically reduces the influence of high order diffracted light on the measurement. Thus, the measured data are always reliable and replicate the real signal under test.

Double Speed Mode

Increases the sweep speed up to 2 times compared to the standard sweep mode, with only a 2 dB penalty to the standard sensitivity value.

Free-Space Optical Input

The AQ6377 uses a free-space optical input structure (i.e. no fiber is mounted inside the instrument), most effective for guaranteeing high coupling efficiency, measurement repeatability, and no maintenance.

This smart solution is:

• WORRY-FREE: no internal fiber can be scratched or get dirty by inaccurate coupling of fibers
• MAINTENANCE-FREE: no internal fiber has to be cleaned
• VERSATILE: the instrument accepts both /PC and /APC connectors
• DUAL PURPOSE: the instrument accepts both Single-Mode and Multi-Mode fibers without being affected by the high insertion loss from MM-SM fibers matching
