How-to Megger a Motor
Web16 jan. 2024 · Now to the motor. Disconnected all 3 line wires, ran test and got .1 megohm on each phase to ground. Then isolated every wire (disconnected 4-7, 5-8, 6-9 and of course line wires). I get 550 megohms on each phase to ground. Is this motor bad? Is the VFD bugging out? Any help is appreciated.

We also check the phase to phase resistance reading and are looking for no more than a 10% difference max. If some of the windings are shorted or you have bad … WebIt is also necessary to check windings for a phase-to-phase short in a similar manner. Separate the motor leads, and connect the megger from the Lead #1 to Lead #2. Likewise, check from Lead #2 to Lead #3, and from Lead #3 to Lead #1. These test results should meet the same minimum value as expected for phase to ground measure-ments. biohacks for health
