    Basic Megger Use

    Good day all. I was wondering how you actually go about using a megger to test the quality of insulation of a motor, I understand why you would do the test. If you were to test it at the motor starter and you have isolated the circuit would you need to disconnect the wires going to the motor...

    Let's say I want to make a board to practice my testing on, what is the best way to go about it?

    Final Ring Test during EICR
