        Abstract: When the high voltage circuit-breaker(especially the vacuum circuit-breaker)switches capacitive current, the transient phenomena of voltage and current will appear which probably causes excessive overvoltage and inrush current, or even causes a restrike threatening the security of power grid. In this paper, the operating condition of capacitive load is analyzed, and the test circuit suitable for 3.6~40.5 kV voltage is designed to meet the requirements of the switch tests, and additionally, the capacitive current switching test of high voltage circuit breaker is discussed. Lastly, this test circuit is applied well in the large-capacity laboratory, and all the testing data of capacitive switching
    conform to the standard.
        Key words: high voltage circuit-breaker; capacitive current switching; direct test; test method
