The aim of this paper is to understand wavelet technique and identification of fault using wavelet transform. This paper presents high speed fault identification and protection of power system lines based on wavelet transform technique. It is a unique method which is used to detect the location and identification of fault in power system. Faults in power system are single line to ground, double line to ground and three phase faults. In this paper the conventional time-amplitude response is presented and the result shows that wavelet leads to identify the type of fault and its location. The results indicate that wavelet technique is fast compared to time amplitude technique.
