A PDE-based partial discharge simulator

In questo lavoro è stato sviluppato un modello completamente basato su un set di equazioni differenziali.

Partial discharges are the main ageing and failure mechanism of solid insulating materials subjected to alternated current stresses. This phenomenon, from a simulation point of view, has been almost always tackled using semi-empirical schemes. In this work, a fully physically-based model, based on a set of conservation partial differential equations, is introduced. A numerical algorithm, specifically designed to solve this particular problem, is developed and its validation is discussed considering some experimental data acquired in a simple geometry containing an isolated void.
