Megger Readings Chart

Megger Readings Chart - Typically start with the lowest voltage your megger has, starting at 50, 100 or 250 vdc will minimize. When the motor is bad it should read. A megger is used to read from phase (winding) to ground. The rule of thumb is 1000ohms per volt. I have looked through a bunch of posts regarding megger testing and not seeing what i am looking for. Megger test megger or insulation testing can be done for 1 min or a 10 min. A hipot tester basically works the same way, but measures leakage. We are being contracted to do repairs as necessary in a house that had been flooded. What should the ohms be going from ground to phase on a digital megger? When we need to check motor, megger is used, why cant we use mutilmeter continuity to check the motor.???
