  • CR4 - Thread: why neutral earthing is required for DG.
    1- The Neutral is Grounded so that there will be a return path for any fault involving a phase line and the gounded body of the equipment supplied with electric power. Protection circuitry are usually made to detect such fault, using the current leaking back to the DG alternator , via the earth and back to the Neutral point.
