Application Guidelines for Ground Fault Protection

today also model intercircuit zero-sequence mutual coupling; thus, the zero-sequence currents obtained from the fault studies already account for these effects. Zero-sequence overcurrent elements can provide very effective resistive ground fault coverage. These elements are capable of being used either independently with time delays or in pilot
