Odd situation, the BESS feeder breaker is tripping on ground fault. There is no ground fault. The relay voltage angles and magnitude seem normal as far as 120deg between phases, but neutral is seeing them in phase. What could the relay be seeing/casue this to happen? The situation happens very consistently every two weeks anywhere between 5 to 5:30 am.
