Checking Unit Sub before... - 01/08/05 03:09 AM
Before starting a unit sub we checked for continuity between phases and ground and kept getting continuity b/w red & grnd. It turns out that it was not a ground fault but only something electronically at the meter. Has anyone encountered this problem before and how do you dertermine if it is a true fault or just this electronic equipment causing this? We determined this by simply turning equipmwnt on after not physically seeing any fault in or around the equipment.
