| Abstract: | Based on the analysis of how to detect highimpedance grounding fault and how to distinguish HIF from switching on shunt capacitors,more reliability verification of normal switching events such as no-load switching on and single-phase automatic reclosing are discussed by applying the difference of transient high-frequency components between fault and normal switching events to improve the reliability of system operation. |

| Keywords: | high-impedance grounding fault shunt capacitors line no-load switching single-phase automatic reclosing |
