| 内容記述 | Abstract A partial discharge appears when the surface of a transmission line insulator is polluted by adhesion of sea salt. A corona noise is made due to the occurrence of the partial discharge on the insulator. The purpose of this research is to develop a monitoring system of the corona noise. To develop the monitoring system, it is necessary to investigate the relationship between the corona noise level and the polluted condition of the insulator and establish the measurement technique of the corona noise. But, it is difficult to extract only corona noise with outdoor observation because there are noises such as rain sound, wind noise and the voice of the insect. The noise measurement experiment was done in the transmission tower, and the shape of waves was analyzed. The corona noise could be extracted in the band of 1kHZ - 3 kHZ from the analysis using FFT and wavelet transfer. It has been understood that the number of electrical discharge counts increases in the place where the partial discharge sound has generated. However, the number of counts increased when the partial discharge sound had not generated with same external noises. It can be distinguished whether it is the partial discharge by examining the interval of 120Hz in number of partial discharges. It is understood to be able to detect the partial discharge sound by using the method. |
