Analysis on High-resistance Grounding of Neutral Ungrounding Systems Based on High-precision Fault Indicator
The present work focused on performing the high-resistance grounding analysis on neutral ungrounding system through synthesizing the signals from high-precision transient fault recorders to cope with small current single-phase grounding short-circuit faults in distribution networks.It mainly studied the faulty line determination and the fault location by collecting recorder signals of various lines and at various positions in the distribution network.Actual experiments dem-onstrated that fault determination through zero-sequence voltage and zero-sequence current facilitates effective reduction in time for fault recovery,and in achieving accurate location of grounding faults in low-current grounding systems.
