A Fault Localization Method for Single-Phase to Ground Faults in LV Smart Distribution Grids [PDF]
, 2020 A fault localization method for single-phase to ground short-circuit (SC) faults in low voltage (LV) smart distribution grids is presented in this paper. Both the use of rms voltage phase measurements and an analysis of symmetrical components of the voltage were investigated and compared in this study.

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

Analysis of Single-Phase-to-Ground Faults at the Valve-Side of HB-MMCs in HVDC Systems [PDF]
IEEE Transactions on Industrial Electronics, 2019 Although the probability of occurrence of station internal ac grounding faults in modular multilevel converter (MMC)-based high-voltage direct-current systems is low, they may lead to severe consequences that should be considered when designing protection systems. This paper analyzes the characteristics of valve-side single-phase-to-ground (SPG) faults
