Computer Simulations of Discharges along Insulator Surfaces
Paper in proceedings, 2018
Development of streamer discharges in air along surfaces of solid insulators is analyzed by means of computer simulations utilizing drift-diffusion model of charge transport in discharge plasma. The results are presented for smooth cylindrical insulator and insulator with a shed. Variations of electron densities, space charges and electric fields profiles during discharge propagation are reported. The influence of a protective shed on the insulator on the discharge development is highlighted.
