Breakdown probability distributions of transformer oil are investigated by applying repeatedly ac voltages with various durations. It is suggested from the test results that the Weibull distribution defined by the shape parameter of ca. 8 fits the breakdown probability distribution of oil. The breakdown probability distributions of oil do not seem to depend on the stressing time.
