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

Simulation and analysis of single-phase grounding fault in small current grounding system
Journal of Physics: Conference Series, 2019 Abstract The characteristics and distribution of single-phase grounding faults in small current grounding system are not easy to capture, and it is not easy to collect and cover all possible situations in operation site. This paper builds a fault simulation model of distribution network based on PSCAD.
