Abstract

This paper was studied on the surface discharge characteristics on the solid insulators in the Liquid Nitrogen($LN_2$) at atmospheric pressure. Liquid Nitrogen has been widely used as a tooling and insulating materials for superconducting and cryogenic cable. Considering the effect of bubbles, we observed tracking Phenomena on the surface of solid insulators and investigated surface breakdown characteristics of several solid insulators.
