how to check the insulation for motor using megger?

Answer Posted / omwikha

It is used to check the insulation resistance between the windings or between the windings and the earth terminal for the case of the motor. One lead of the megger is put on the earth terminal and the other lead is moved from one winding terminal to another as the megger handle is rotated for generation of voltage used for testing, the readings are noted and compared with the reference values to ascertain the condition of the motor.low values means insulation failure.
