【Abstract】 The paper presents a method to compute the fractal dimension of partial discharge with wavelet transform and fractal.Because the fractal dimension of different partial discharge is different,the fractal dimension can be used for identifying partial discharge signals and correlation processing The experiment results show that the method can identify accurately partial discharge signals and can find out corresponding relationship of electricity and ultrasonic signal,as a result of improving the locating precision.更多还原
