Question

the output current of an AC motor's frequency inverter should be measured using a/an?

Answer 1

Ac motor frequency inverter is device used to control speed of AC motor without affecting the electric consumption ,torque, impedance, magnetic flux of motor.and the output current is measured using digital multimeter with a V PMW .

These are helpful in overcurrent protection, especially helpful while controlling motor with High inertia.

Their working is divided into three main stages and they are an input converter ,a dc bus and an output inverter.

It act as a barrier in between all input voltage disturbance like Harmonics, ripples ,sags,surges.
