Abstract

The propagation of streamers on a surface of a solid insulator (hard glass) vertical or parallel to an electrode axis in a point-plane gap in perfluorocarbon (PFC) liquid, has been observed in detail, by using a high speed schlieren method. Especially, the effects of the point polarity and the existence of the solid insulator on the streamer propagation are investigated and also the creepage discharge in PFC liquid is compared with one in transformer oil.
