Transmission systems (TS) plays a major role in electrical power systems. The interruption caused to the consumer because of TS faults is substantial. So TS needs a proper protection scheme to ensure continuous power supply to the consumers. This study proposes a novel scheme using wavelet technique for classification of faults in TS. In order to do so, the proposed scheme uses current measurements of just one side of the transmission line. Simulations are performed under different fault conditions using MATLAB. The stability of the proposed scheme under various cases is tested andreliable results have been obtained.
