The present paper presents an accurate hybrid framework capable to rapidly detect, classify & locate shortcircuit faults on transmission lines. The proposed algorithm has employed the values resulted from each three- phase currents wavelet transform in order to obtain instantaneous fault detection. Singling out short-circuit faults based on the measured voltage waveforms and three-phase current is done when fault events occur in power transmission lines. The energy derived from three-phase currents and three-phase voltages wavelet transform has been used as the classification algorithm input .Then fault location has been activated as the result of fault classification method. Combining the methods …
