Performance of a fault diagnosis method based on wavelet characterization

This paper shows performance of a fault diagnosis method in a typical application in which fast detection of fault is necessary. The fault diagnosis method is based on characterizing the signal features using wavelet transform. The power system is a static transfer switch (STS) which requires a fast detection of the fault instant. The method is experimentally verified and compared to a conventional method. Results approve superiority of the wavelet characterization method.
