A method of single-phase grounding fault line selection based on optimization spiking neural P systems

Frontiers in Energy Research, 2022
It is important to select the fault line rapidly when single-phase grounding fault occurs in the small current grounding system. The fault information acquisition of existing methods generally need hardware modification, so the high cost makes it ...
