| Abstract: | The power cable of base station through the trees, the mountains, it is difficult to find fault point when oc- cur failure. With ring resistance and cable diameter and environment temperature can calculate the fault location, this paper introduced the calculation method of cable fault location, and according to the calculation method, made the corresponding table for loop resistance, temperature and length of cable fault location. |
