Yokogawa WT5000

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

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.

Current sensor module with DC power supply

Use of the internal DC power supply for AC/DC current sensors simplifies the preparations before measurement and the measurement setup only requires the current sensor and a connecting cable. Using an external DC power supply and additional wiring is no longer required. There are three sensor connection cable lengths available; i.e., 3 m, 5 m, and 10 m.
*Firmware version 3.01 or later is required.

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.

Advanced Filtering

In addition to low pass frequency filters and line filters, the WT5000 features advanced filtering capabilities that provide 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 wide band and harmonic measurements. Users can limit the number of harmonic orders to eliminate attenuation in low bandwidth measurements.
