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.
