要約(日本語): Partial Discharge (PD) measurements in Gas Insulated Switchgears (GISs) are very promising for insulation condition monitoring. Accordingly, we have been investigating the PD characteristics for electrode/epoxy delamination of GIS spacers as one of the severest defects in GIS. With infiltrating SF6 gas from the surroundings into the delamination, the gas pressure inside delamination changes from sub-atmospheric pressure to filled SF6 gas pressure in the GIS tank. Therefore, the PD activity, represented by PD generation rate and PD current, is acquired and analyzed at different gas pressures.
