3 Phase Noise
3 Phase Noise
(OP)
I have attached a 3-phase reading between an MCC and a motor drive. Phase B is causing the ground fault; which is what's causing the thin high peaks on the readout. The drive is on the load side of a reactor. What I can't figure out is why Phase C is almost flat line while Phase A reflects Phase B but inverse. Does anyone have any suggestions?
Thanks
Thanks

That crossed my mind but I was not sure about that. I'll have someone check that to see if that could be it. Thanks for the suggestion.
