| Abstract: | An economical and effective new technology using sound card is proposed in this paper.It collects the leakage current from high voltage insulator,and then deals with the noise elimination using wavelet analysis.Compared with the traditional signal analyzing method,the wavelet analyzing technology not only can distill the leakage current signal from the noise precisely,but also can distinguish the low quality character of leakage current signal.This method plays an important role to the device in early fault diagnosis,and can improve the accuracy of measurement and fault diagnosis in the application. |
