Review for verification of capacitive current performance by using synthetic testing method

Several synthetic testing methods have widely been used for the performance evaluation of ultra high-voltage circuit breaker. Among these synthetic method, in the paper, capacitance switching testing method which can meet the test requirements and increase the testing capacity has been proposed. This method is made up of two separated sources of short-circuit generator for current source and L-C resonance circuit for voltage source. By using this method, KERI will perform the performance evaluation of capacitive current switching performance for the 800kV GCB(Gas Circuit Breaker).
