Abstract
Capacitive current switching test is an important test for high voltage ac circuit breaker.In recent years,the EHV and UHV circuit breakers have encountered many problems when they switching capacitive curent in system and test,such as frequent restrikes under special environment condition and non-sustained disruptive discharge(NSDD) and restrike after more than one cycles of recovery voltage.In this paper,these typical problems are researched and analyzed,the imperfections of current relevant standards and test methods are discussed,the new tests and experiences of the circuit breaker used for switching filter bank are introduced.This paper is a meaningful exploration for the improvement of the current standards and test methods.关键词
