This paper proposes a novel algorithm for EHV transmission line faulted phase selection based on current transients by employing the wavelet transform (WT) and the artificial neural network (ANN) techniques. The WT technique and spectral energy calculation offer an efficient method for feature extraction and the ANN plays an important role for decision making. The system is simulated using EMTP and the proposed faulted phase selection scheme is developed based on MATLAB. All the test results show that the designed algorithm is very suitable for identifying the faulted phase(s) under a wide variety of different system and fault conditions in EHV-transmission lines.
