With the increasing application of the power cables to the power supply in developed city, it is necessary to constantly improve the accuracy ranging of power cable fault location. It is presented that the relevant technology of the wavelet transformation and autocorrelation analytical method using in distribution network cable faults location. It was applied to filtering signal and detect singularity, that the autocorrelation analysis as the constraint condition of wavelet transform. In the end, the automatic and accurate ranging of cable fault location was carried out. The results of simulation show that this method can obtain high precision of fault location.
