Hello, I would like experts to review my schematic for a Star (Y) 3-phase 4-wire and Delta (3-phase 3-wire) 600V system.
The line-to-line voltage for the Delta 3-phase, 3-wire configuration is 600V, and my current transformer (CT) ratio is 500:5.
My main concern is regarding the Delta configuration: if we apply the phase B voltage to the neutral, what will be the behavior of the system on my board following this schematic?
