I lost one phase of power yesterday, so only half of my circuits are working. We've had heavy windstorm where I'm at and I'm trying to diagnose the issue. I'm assuming there is a loose connection at my overhead service line. Power company is supposed to be coming out eventually but they are quite busy with all the outages.
When I measure line-to-line it should read 240V, but it reads 2V. When I measure each phase to ground they are 120V for the good phase and 118V for the bad phase. Why am I getting a reading of 118V?
I shut off all the circuits to the bad phase. If I turn on some of the circuits, the line-to-ground voltage of the bad phase drops. If I measure voltage on some of the circuits that are turned OFF from the bad phase, I am getting up to 20V.
