and lowered. The test method is also useful in determining quantities such as apparent charge and pulse repetition rate together with such integrated quantities as average current, quadratic rate and power. The test method is useful for test voltages ranging in frequency from zero (direct voltage) to approximately 2000 Hz.
1.2 The test method is directly applicable to a simple insulation system that can be represented as a two-terminal capacitor (1), (2).
1.3 The test method is also applicable t
