Why is rotor is blocked in brake test on 3phase induction motor?
That's interesting. Can you explain how an insulation resistance test works?
Sure. An insulation resistance test is used to measure the resistance of the motor's insulation system, which includes the insulation on the stator windings, the insulation between the windings, and the insulation between the windings and the ground. The test involves applying a high voltage to the motor's terminals and measuring the current that flows through the insulation. The higher the resistance, the better the insulation is.
