Fault Classification in Transmission Systems using Wavelet Transform

Abstract

Fault analysis is a prime apprehension in power system. This article elaborates an appropriateapproach for detection of faults and wavelet technique is used for classification of faults inoverhead lines. This method uses only measurements of post fault currents at single end of theline for fault analysis. To validate the efficacy of this method, simulations have been performedunder various conditions of fault occurrence using MATLAB and the obtained outcomes arecompared with fuzzy logic technique. The outcomes attained are promising and as well accuracyimproved in classification.
