초록
In this paper the controlled closing algorithm to locate contact touch instants within the span in which the making voltage is minimized is proposed with the characteristics of circuit breakers such as RDDS(rate of decrease of dielectric strength) and a mechanical operating tolerance taken into account. The analytic results on the voltages across circuit breaker terminals upon closing operation play an important roles as references to describe the suggested method. Even though in the case of the isolated neutral capacitor banks, it is possible to decide the optimum contact instants without any dedicated procedures.
