Grounded 3 phase delta
WebJan 19, 2024 · Our electric supply is 480V B-Phase Ground (Corner Grounded) Delta. Let's assume I have to use a 230V 3 phase motor. If I buy a square d transformer like Square D 3T5F transformer, I am trying to understand if I need to ground my B phase on either side of the transformer or both. So the incoming lines are 480V - A, 0V - B, 480V - …
