Abstract The power cable bears the responsibility of power transmission. The failure of power cable seriously affects the normal supply of electric energy. How to find fault and locate the fault quickly and accurately is the key issue of power cable maintenance. In recent years, the method of traveling wave fault location for power cable has been developed rapidly, and the advantages of the cable fault location method based on wavelet transform are most obvious. According to the characteristics of cable faults, a location model of power cable fault traveling wave is established by using Matlab software, which realizes the on-line location of faults and has certain application value.
