Abstract

This paper describes a testing method to assess the reliability of the epoxy bushing used for the vacuum circuit breaker(VCB). Especially, in order to show the long-term durability of epoxy bushing in a short testing duration, the extremely accelerated electric stress applying test plan was adopted.
