This procedure\r\nis required to be precise with no time consumption. In this paper\r\ndetection of fault type has been implemented using wavelet analysis\r\ntogether with wavelet entropy principle. The simulation of power\r\nsystem is carried out using PSCAD\/EMTDC. Different types of\r\nfaults were studied obtaining various current waveforms. These\r\ncurrent waveforms were decomposed using wavelet analysis into\r\ndifferent approximation and details. The wavelet entropy of such\r\ndecompositions is analyzed reaching a successful methodology for\r\nfault classification. The suggested approach is tested using different\r\nfault types and proven successful identification for the type of fault.","references":"[1] M. Kezunovic and I.
