    Abstract: The combined voltage test is one of the most important dielectric type tests of switchgear breaker.During the impulse plus power frequency combined voltage test, due to the capacitance coupling between the two high-voltage power supply circuits, the impulse voltage will cause a voltage drop at power frequency side during the test, and appropriate voltage drop compensation measures should be taken. This paper briefly discusses the value of peak coefficient of reverse power frequency voltage in combined voltage test.Taking the lightning impulse combined voltage test (LIWV+AC) of a 1 100 kV GIS type disconnector as an example, through the actual test combined with the equivalent circuit calculation and ATP-EMTP simulation, the influence of capacitance across the open switching device and the additional capacitance on power transformer side voltage drop is mainly studied, and the reasonable test method is given.Finally, the problems that should be noted in the actual test are summarized.
    Key words: across the open switching device; voltage dorp; capacitance coupling; combined voltage test
