WebImpulse testing of transformers is done using both the full wave and the chopped wave the standard impulse, produced by a rod gap with a chopping time of 3 to 6 μs. To prevent large overvoltages being induced in the windings not under test, they are short circuited and connected to ground. WebThe waveform observed should be identical to applied waveform (other than for amplitude) : then the device has passed the test. (3) Chopped wave test at 115% fullwave amplitude : For this kind of test , the impulse generator would have to be fitted with a rod gap or controlled trigatron type gap.
