Finite-element analysis for surface discharge on polyimide insulation in air at atmospheric pressure under pulsed electrical stress

A surface discharge non-equilibrium plasma model of air–polyimide under pulsed electrical stress is established, by considering the reaction of charged particles on the dielectric surface and the secondary electron emission caused by the condition that high-energy particles bombard the material surface. The model defines the chemical reaction of air discharge by using simplified set of reactions, ...
