High-Resistance Grounding Fault Detection and Line Selection in Resonant Grounding Distribution Network

Electronics, 2023
The detection and selection of fault lines in resonant grounding distribution networks pose challenges due to the lack of sufficient state parameters and data. This paper proposes an approach to overcome these limitations by reconstructing the initial criterion for fault occurrence and fault line selection.
