The Yokogawa WT5000 Precision Power Analyser - Winner of Elektra Awards Test Product of the Year 2019

As renewable energy, electric vehicles and energy efficient technologies gain wider adoption, the need for reliability in testing efficiency, performance and safety has never been greater.

Changing application needs and evolving international standards call for custom measurements and consistent accuracy. In the WT5000 Precision Power Analyzer, engineers have a versatile platform that not only delivers reliable measurements today but, is ready for the challenges of tomorrow.

With its unmatched accuracy and modular architecture, the WT5000 empowers engineers to innovate with precision, flexibility and confidence to quickly bring their products from concept to market.

The Yokogawa WT5000 Precision Power Analyzer Delivers:

Reliability – With a guaranteed accuracy of ±0.03%, harmonic comparisons up to the 500th order and custom computations, the WT5000 delivers multichannel measurements that you can trust.

Versatility – 7 slots for user swappable power elements and diverse options enable you to expand or reconfigure the WT5000 as your applications and their needs change. Additionally, the speed and torque from 4 separate motors are measurable.

Simplicity – With a full touchscreen experience, supported by hardware hotkeys and powerful software for remote measurements, connecting, configuring and measuring power has never been easier.

Precision at your fingertips


Multi-channel Measurements

Measure from up to 7 different power phases at 10 MS/s (18 bits). The high resolution, 10.1 inch WXGA display allows split screen viewing of up to 7 waveforms and can display up to 12 pages of diverse measurement parameters, making it ideal for efficiency tests of inverter driven motors, renewable energy technologies and traction applications like pumps, fans and electric vehicles. Measurements are also displayed in vector format or trending in time.

Multi-channel Measurements


Intuitive Operation

Operable by touch and/or hardware hot-keys independently, the WT5000 offers a seamless and intuitive experience that makes connecting, configuring and measuring easier than ever before. The 10.1 inch WXGA touchscreen delivers excellent noise immunity even in high noise environments such as motors and inverters.

Intuitive Operation


Unmatched Accuracy

The WT5000 is the world’s most accurate precision power analyzer with a basic power accuracy of ±0.03%. Its accuracy specifications are guaranteed from 1% to 130% of the selected voltage and current ranges. With minimum influence of low power factor (0.02% of apparent power) the unit is also accurate at large phase shifts and frequencies.

  • AC power accuracy: 0.01% of reading + 0.02% of range
  • DC power accuracy: 0.02% of reading + 0.05% of range
  • 10 MS/s 18 bit ADC

Unmatched Accuracy


Custom Triggers and Computations

Define and use event triggers and custom computations as per application needs. The event trigger function allows users to set limits to capture readings that fall within or outside a specific range of power, current or other parameters. Users can also define and use up to 20 different expressions for custom calculations. Data that meets the trigger conditions can be stored, printed, or saved to a USB memory device.

Custom Triggers and Computations


Advanced Filtering

In addition to low pass frequency filters and line filters, the WT5000 features advanced filtering capabilities that provides unprecedented control to analyze even the toughest of waveforms with precision.

  • Synchronization source filter: Instead of synchronizing to zero crossings, users can select any specific point of the synchronization source signal.
  • Enhanced frequency filter: Allows users to simultaneously measure fundamental and switching frequencies without influencing any other parameter.
  • Digital Parallel Path filters: Supported by a high-frequency anti-aliasing filter, two separate line filters for normal and harmonic measurements ensures accuracy without aliasing in wideband and harmonic measurements. Users can limit the number of harmonic orders to eliminate attenuation in low bandwidth measurements.

Advanced Filtering


Advanced Harmonic Analysis

Evaluate and compare input and output harmonics of inverters, motors or power conditioners up to the 500th order. The WT5000 allows users to not only measure harmonics and power simultaneously but also offers side by side comparison of harmonics from two different input sources. The effects of noise and aliasing are minimized by antialiasing and line filters with Digital Parallel Path technology allowing simultaneous power analysis of wideband and narrow band components.
