| Abstract: | A detecting system of PD for model GIS has been set up. Investigation was made on the diagnosis of the PD in GIS. The measurement included the Ultra High Frequency (UHF) detection, conventional PD measurement and the power phase analysis. The sort of PD is classified by the PD characteristic research. Then Discharge level of UHF signal is estimated based on its sort and the conventional PD measurement. The practicality of UHF detection is development in the engineering. |
