Ground leakage current
WebJan 7, 2024 · In the event of a ground fault, current from the faulted machine flows through its ground connection through the ground resistor and into the neutral point of the transformer. In place of a breaker trip or a fuse blown, ground fault protection is provided by a residual current device (RCD). http://a.flukebiomedical.com/Introduction_to_Electrical_Safety_Testing_-part_2
