Abstract: This paper presents a new fault detection and classification algorithm based on the wavelet transform. The B-spline wavelet transforms of three phase currents on transmission lines are employed. By comparing the moving average of these transforms, fault types are classified easily. Effects of the fault inception angle, fault distance, and fault impedance are examined. Simulation studies using EMTP show that the wavelet-based algorithm is simple, effective, and robust. Without any modification, the proposed algorithm can be applied to power systems of any voltage level. It is suitable for the high-speed protection relaying. Copyright © 2000 Taylor & Francis.
