The mechanism of clearing in metalized film capacitors
Self clearing in metallized film capacitors results in gradual failure from capacitance loss rather than sudden failure after the first breakdown. During clearing, the arc normally extinguishes with little change in the potential across the capacitor, i.e., the source potential (and impedance) for the clearing discharge is approximately constant. Usually an arc driven by constant source ...
