Measurement of efficiency of large inverter-driven motors

The WT2000 series enables you to set the measurement range for each input element, permitting accurate measurement according to the level of each input signal. The 3-phase 4-wire model permits measurement of single-phase power and 3-phase power (3-phase 3-wire, 2-wattmeter method), and the MATH function enables you to perform input-to-output efficiency calculations. When you need different sensors to measure large currents and high voltages, please contact your local YOKOGAWA representative.

Power calibration system

The WT2000 series has a high basic power measurement accuracy of 0.04% of rdg + 0.04% of rng (cos f = 1, 45 Hz to 66 Hz), and also the effect of power factor is small, being 0.1% of rng (cos f = 0, 45 Hz to 66 Hz), hence you can use the instrument as a standard for calibrating various wattmeters, reactive power meters, and power factor meters.

Measurement of cooling and heating performance of air conditioners The WT2000 series has a wide bandwidth (DC and 2 Hz to 500 kHz) and high accuracy (0.04% of rdg + 0.04% of rng), and can directly measure inputs of up to 30 A. It is therefore suitable for evaluating the stability of an air conditioner in an environmental test chamber during measurement of the cooling and heating performance, and also for measuring electric power and electric power quantity after evaluating the stability.
