초록
High-voltage gas-insulated circuit-breaker must interrupt short-circuit current successfully when breakdown occurs in electric power system. Among many test-duties, Basic Terminal fault T100a(BTF T100a) is the one of the severest duties because of its high DC component of short-circuit current. In this paper, we developed 245kV 50kA gas circuit breaker using control circuits to reduce DC component while interrupting short-circuit current, then got good performance through high-power tests in Korea Electrotechnology Research Institute(KERI) and KEMA
