Estimation and d termination of fault in an underground cable is very important inorder to clear the fault quickly and to restore the supply with minimum interruption. This paper presents determination and location of fault in underground cables by wavelet transform as it is one of the most efficient tools for analyzing non stationary signals and it has been widely used in electrical power systems. The cable is modeled in MAT LAB simulink using simpower system tool box. Mexican hat and coif let wavelet transforms are used to extract the signals and the waveform are shown. The simulation results show that this method is efficient and powerful tool to estimate the faults when they occurs in the underground cables.
