Abstract

In order to newly define and specify the performance and the testing method of the high-voltage circuit breaker, IEC 62271-100 was published in May, 2001 and took place of IEC 60056 which had been used since 1987. This new standard intensifies the requirement and the test method of the circuit breaker and also domestic manufacturer makes progress the new product development. And, KERI also goes on the build-up project of short-circuit testing facilities for fulfilling the testing method requirements in new IEC 62271-100. This paper introduce the limiting method of short-circuit making current by controlling the time constant of dc component.
