Grounding Grid Topology and Fault Detection System Based on Inductively Apparent Magnetic Impedance Method

Based on the inductively apparent magnetic impedance method, a detection system that can distinguish the grounding grid topology, detected break-points and corrosion points. And carry out simulation calculation and simulation grounding grid on-site test for the detection system. The results show that the topology of grounding grid could be distinguished through simulation results and test data and the fault diagnosis of break-points and corrosion points, which verified the reliability and accuracy of the detection system.
