Abstract :
The measurement includes the UHF detection, conventional partial discharges (PD) measurement and the power phase analysis. The corona discharge characteristic of model GIS is researched. Then discharge level of UHF signal is estimated based on comparing of UHF detection and the conventional PD measurement.
