Abstract: This paper proposes a method for classifying Transmission Line faults using Discrete Wavelet Transformation. The method utilizes current travelling wave generated during the fault conditions. Wavelet Transform is used for extracting these transient signals. An algorithm for classification of Transmission line faults is presented which utilizes the modulous maxima of current travelling waves as threshold values. The method is more efficient and accurate for classifying and phase selection of Transmission Line faults
