WebJun 29, 2024 · What is Neutral and why it is grounded? In 3 phase AC system, we know the phase difference is 120 degrees for all the phases. In Delta-Star Transformer, a center or common point is available from where the same potential difference with a shifting of phase angle 120 degrees is found for all the three winding of R, Y & B Phase.. During the … WebFeb 29, 2024 · With a floating delta system, you are required to provide ground fault detection. With a corner grounded system, the OCPD should open in the event of a ground fault, thus providing a safer system. What is the phase voltage of corner grounded delta? I guess it sort of is “neutral”, but its a phase conductor. danyfortin_cmm
