Reproduction Methodology for Single Phase-to-Ground Faults in Overhead Transmission Lines
IEEE Access, 2017 Reproducing key fault information quantitatively has practical significance for the fault diagnosis of overhead transmission lines (OLTs). In order to reproduce the key fault information of a single phase-to-ground (SPG) fault, this paper proposes a reproduction methodology based on the waveform inversion theory and the propagation characteristics of a
