The characteristics of 10 kV power distribution system of Hunan area are analyzed and the advantages and disadvantages of fault identifying logics for power cable fault indicator are expounded and a new fault indicator setting principle which is suitable for the grid is put forward. The correctness of the fault identifying logics and setting principle is verified with the ATP/MATLAB software simulation analysis. The experience in the process of the installation operation maintenance and application is summarized out and a fault locating method based on the mathematics principle of dichotomy is proposed to improve the working efficiency of power distribution network fault recovery work.
