1 Application Notes 1 von :12 XY-Capacitor Surge Test (IEC ) A full automatic Surge test for X/Y-Capacitors for eight samples up to 12kV (IEC ) 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%. The files are HTML-files just as generated by TEMA protocol engine. (TEMA = EMC-PARTNER Test Manager) Capacitor: RIFA PME271M, 600nF, 275Vac ; Test voltage : 2500V Files: APP30-1.htm : overall protocol of the 8 samples APP30-2.htm : detail protocol of Sample 2 APP30-3.htm : detail protocol of Sample 3 APP30-4.htm : detail protocol of Sample 4 APP30-5.htm : detail protocol of Sample 5 Sample 2 :all pulses have passed Sample 3 : The capacitor is broken at the second pulse.the oscilloscope shows an full short circuit.the test on this sample is stopped. Sample 4 :The first pulse shows an self-healing. The following pulses are o.k. Sample 5 : At this sample there were no 3 good pulses in a sequence, so all 24 pulses were need to test. Because more than 3 are good, the sample has passed.
