I was asked if I had a megger so that I could test the compressors on a chiller. I would assume they want a insulation test on the windings. I have not used a megger before. Would someone be able to give me some hints on how to use a megger when testing compressors. I have a amprobe megger that has high and low voltages. It is 3 phase chiller so I assume that the compressors are 3 phase.
