General

Test Procedure:  

"Each individual capacitor shall be subjected to a maximum of 24 pulses of the same polarity. The time between impulses shall be not less than 10s. If any three successive impulses are shown by the monitor to have had a waveform indicating that no self-healing breakdowns or flashovers have taken place in the capacitor then no further impulses shall be applied and the capacitor shall be counted as passed. If all 24 impulses have been applied to the capacitor and three or more of them are of waveform indicating that no self-healing breakdowns or flashovers have taken occurred then the capacitor shall be counted as passed, but if less than three impulses are of the required waveform then the capacitor shall be counted as a defective."

Waveform monitor:

An oscilloscope compares the waveshape with a reference waveshape taken from a good sample. If there is any amplitude difference greater than 10% the capacitor has failed. Further the peak value of the pulse has to be within +/-10% and the duration within +/-20%.
