Abstract: Electrical power system consist various component. From this component Transmission lines are designed to transfer electrical energy from source locations to distribution networks. Therefore these are vital component of electrical power system. Most of time transmission lines are exposed to various faults in overhead transmission line system. Hence various protective scheme and devices such as protective relay and fault recorder systems, based on fundamental power frequency signals, are installed to separate the faulty line and provide the fault position. However, the error is high especially in transmission lines, so to provide a good quality of electricity as well as to prevent accidents, a study of protective scheme is very important. This paper provides a brief review of various faults and wavelet based fault detection methods used for their detection.

Keywords: Wavelet transform, fault detection, power system, ANN.
