Abstract: Wavelet transform technique is a robust and versatile method to analyze non-stationary,non-periodic wide band signal such as transient signal. Wavelet transform which is new tool for caballing both time and frequency information simultaneously. The suitable wavelet for analysing power system transients is Daubechies(Db) wavelets. This paper focused on transmission line faults classification using wavelet analysis. The different faults in the transmission line (TL) are detected and classified using fault classification algorithm based on wavelet MRA(Multi resolution technique) technique.
