Ghost Phase Wiring
Ghost Phase Wiring
(OP)
I have a job site where the compressor burnsout every year. When I check the wiring between phases I get 460 Volts. Two phases to groung I get 460 volts; however, when I check the third phase to ground I get 0 volts. I have a 75 horsepower motor. could the wiring be problem for my burnouts





RE: Ghost Phase Wiring
Look more for a current or voltage imbalance between phases.
Also look for short cycling. The compressor should not be starting and stopping more frequently than every 15 minutes.
Look for a a bad head unloader. If the compressor isn't being unloaded one event could be fatal.
