Research on the Characteristics and Identification Methods of Power Cable Grounding Fault
In view of the serious impact of frequent cable faults on power supply reliability and economic bene-fits in the current power system,this paper proposes a fault identification method based on cable zero-sequence current and voltage waveform analysis by deeply analyzing the electrical characteristics of cable grounding faults and combining high-precision signal processing technology.It can effectively distinguish the continuous grounding fault and intermittent grounding fault of the cable,improve the efficiency and accuracy of fault detection in the pow-er system,and provide theoretical basis and technical support for the rapid diagnosis of power cable faults.
