| Abstract: | In order to quickly locate the cable fault point, and in connection with the feature of a 10 kV contribution network in Hunan Province, this paper proposes a new cable fault indicator setting principle for the network, and does simulation analysis with ATP/MATLAB to verify its correctness. Summarizing the experience in installation, operation, maintenance and cable fault indicator application, the paper puts forward a new fault locating method based on dichotomy principle to improve the efficiency of removing the cable fault. |
