Abstract Previous work has shown that prebreakdown, electrical aging, and breakdown phenomena are directly associated with charge carriers injected from contacts their subsequent dissociative trapping recombination. In addition, the energy released each or recombination event is dissipated in breaking of bonds macromolecules, thus forming free radicals new traps electrically stressed insulating polymers, as predicted by Kao's model. It this gradual degradation process leads to aging...
