A new method for single‐phase high resistance grounding fault protection in low resistance grounded distribution networks [PDF]
Engineering Reports, 2023 The neutral point of the distribution network is grounded with low resistance, which can quickly remove single‐phase grounding fault and effectively suppress overvoltage. However, the existing zero‐sequence overcurrent protection has a high setting value.

High-Resistance Grounding Fault Detection and Line Selection in Resonant Grounding Distribution Network [PDF]
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.
