Abstract: Cable is an important part of the power system. In order to ensure the safety and stability of transmission and distribution, it is very important to design an online detection system for cable faults. Therefore, an online detection system for cable fault is designed, by analyzing the cable fault and cable partial discharge characteristics, four characteristic quantities of cable capacitance leakage current value, partial pulse current, ambient temperature and ambient humidity are selected for detection. The detection system can monitor the cable insulation status online based on these data, so as to effectively reduce and prevent the occurrence of leakage accidents.

Keywords: cable fault; partial discharge; online monitoring; Proteus
