| Abstract: | The white noise interference in GIS PD is analyzed. Simulative experimental results show that it is strong for the analysis method of wavelet to supress white noise interference,the signal distortion is little and can pick up PD signal from the white noise interference effectively. |
| Keywords: | GIS partical discharge wavelet transformation white noise threshold fllter |
