ABSTRACT
ABSTRACT: The status of high-voltage circuit breaker is becoming more and more important in electric power system. It not only controls the switching of high-voltage power system but also protects the whole high-voltage power system. The breaker is required to control the whole system timely no matter when the system is in load condition, or in light condition, or even in open circuit fault. The breaker is able to react in time when the system is in certain emergencies. Therefore, the operating condition of high-voltage circuit breaker has direct impact on the safety of the whole system.
