Abstract: In view of the situation that operation and maintenance personnel may cause serious consequences such as electric shock and explosion when operating on the power distribution cable. This paper introduces a medium-voltage faulty cable identification accident, expounds the power failure cable identification principle and the wiring method of the power failure cable identification, and analyzes the cause of the accident from two aspects of cable path detection and cable identification. Based on the actual situation, several suggestions are put forward to ensure the correct identification of faulty cables and prevent the occurrence of safety production accidents in the power grid, and provide references for personnel working on cable identification.
Key words: cable identification; power distribution network; path detection; locate fault
