Abstract

This paper presents an algorithm to determine the fault type on transmission line based on wavelet transformation analysis. The algorithm is developed by analyzing the three phase currents (Ia, Ib and Ic) using Wavelet Transformation, and then start to study the faulted phase(s) at different location (each 5% of the transmission line (TL) length). Fault simulation is carried out by EMTDC/PSCAD program. Two seconds window of waveform covering pre-fault and post-fault is used. The discrete wavelet transforms (DWTs) are used for data pre-processing. Four types of mother wavelet are used for signal processing to identify the effective wavelet family that is most suitable to be used in estimating fault type.
