Distance Protection Impedance Measurement Fundamentals: Phase-to-Phase and Phase-to-Ground Faults
Distance protection measures loop impedances to determine the location of a fault on the protected line. There are six loops: A-B, B-C, C-A, A-G, B-G, and C-G. This article demonstrates how distance protection measures the apparent loop impedance for B-Phase-to-C-Phase and A-Phase-to-Ground faults. The loop impedances for phase-to-phase and phase-to-ground faults are not equivalent due to the presence of neutral …
