ABSTRACT
This paper presents a study on fault detection and location by using PSCAD to obtain the current signal in the transformation of signal interference. This study was done by using the Clarke’s transformation method to transfer the current signal phase (three phase) signal into a two-phase current, alpha current and gamma current (current Mode). New method with fault current approach is introduced in this paper. Mode current in transform signal using discrete wavelet transform (DWT) was utilized to obtain the wavelet transform coefficients (WTC)2, to determine the current time when the disturbance amplitude values (WTC) 2 reached a maximum point value. Mother wavelet was used to compare the Db4,  Sym4, Coil4 and Db8. The fault location was determined using the Clarke transformation, then transformed into wavelet, which was very accurate and thorough. Analysis was also conducted for some other mother wavelets. The error of the simulated wavelet fourth parent was found less than 2%. The most accurate parent was wavelet Db8 with the fastest time of detection and the most minor error, whereas the largest error was found in the parent wavelet Coil4.
