The increasing need for energy conservation in recent years has resulted in a daily increase in power converter operating frequencies for achieving miniaturization and higher efficiency. Therefore the need for high accuracy power measurement, e.g. of the distorted waveform, in higher frequency is increasing.

Taking for example inverter driven motors, the carrier frequency goes up to 15 kHz by adopting IGBT, on the other hands, evaluation in low speed rotation is also in demand. Therefore users are looking for power meters with wider than usual bandwidth.

We developed a new power meter with high basic performance, high noise immunity and high reliability. The model WT1000 achieves high speed, high accuracy and wide bandwidth measurements by using a digital sampling system. Furthermore it has motor evaluation function measuring output signals from a torque meter (torque and revolution speed) and compute total efficiency of the motor.
