Abstract :
The effect of surface contamination on GIS spacers has been investigated using UHF partial discharge measurements. The discharge characteristics have been recorded, enabling surface contamination to be distinguished from other sources of partial discharge. In addition, a method of determining the flashover probability is discussed
