Precision power analyser

19 October 2005 Test & Measurement

Yokogawa's WT3000 precision power analyser combines high accuracy (±0,02% of reading +0,04% of range) with a wide DC, 0,1 Hz to 1 MHz frequency range. The WT3000 can carry out up to four power measurements simultaneously, is easy to operate with direct keys, and offers a variety of display formats on a 210 mm colour TFT. The instrument includes powerful integrator functions as standard, plus a wide range of options to enhance application-specific measurements.

Two versions are available: the standard model, which is suited to high-accuracy measurements of the input/output efficiency of invertors; and a dedicated motor version, which incorporates facilities for measuring torque and speed and converting measurements into mechanical parameters with a data update speed from 50 ms to 20 s.

Measurements can be made over seven current ranges from 0,5 to 30 A r.m.s. and eight voltage ranges from 15 to 1 000 V r.m.s. Guaranteed accuracy for AC voltage, current and power is between 1% and 130% of the input range. The continuous maximum common-mode voltage of 1000 V r.m.s. at 50 Hz/60 Hz enables precision power measurements in the evaluation of inverter and motor efficiency characteristics. The low power-factor error (0,03% of apparent power) enables precision power loss measurements.
