Abstract :
Detection of defects in insulating system has long been recognized as an important part of quality control for high voltage equipment. In this paper, an acoustic signal analysis method for detection of defects in insulation system based on wavelet transform is introduced. Some applications of wavelet transform in detection of defects in insulating system are given. Compared with the conventional detecting methods, the acoustic signal analysis method based on wavelet transform has advantages such as higher resolution and convenience for practical use
