When we try to start it, Main Incomer was tripped showing Earth fault. During trouble shooting, I found that there is 180 degree phase shift for one phase. We see that in trace diagram that phase diff bet RY was 120 but phase B was 180 shifted Is it because of Drive? In drive, is there any component which causes this? Regards, Devesh Vithani
