Modelling of physical and chemical processes in self-healing breakdowns in organic dielectric materials

Abstract

A model is developed for a theoretical description of self-healing breakdowns in organic dielectrics. The spatiotemporal distribution of potential and current during the self-healing breakdown is first investigated, and then the energy converted for the evaporation and ionization of electrode metal as well as for gas-dynamic decomposition of the material is determined. The gas formation results may be used to compute graphite deposition in the insulating areas.<>
