High voltage testing of capacitors

Three different types of capacitor have been tested to determine maximum usable high voltage. The capacitor testing was performed in the dynamic mode. The voltage rise varied from 200 to 400 V/sec. Disc ceramic and thin film capacitors of different value and different nominal voltages were tested. Experiments have shown that the breakdown voltage for all types of the capacitors tested is about ten times more than the nominal voltage of the capacitors. Data are given for the limiting high voltage for each kind of capacitor. Experiments have shown that the mechanisms for the destruction of each type of capacitor have specific features.
