Simulation modeling of an insulation system with the development of a partial discharge in the volume of a solid dielectric

Partial discharges are electrical discharges in an insulation system confined to only a portion of the dielectric. They develop into gas bubbles formed in the volume of the solid dielectric. The Partial discharges are one of the main causes of insulation aging. Their single action has no practical effect on the insulation, but their prolonged action, accompanied by an increase in their intensity, leads to a slow destruction of the insulation and to its complete penetration. The article proposes a modeling of an insulation system with the development of a partial discharge in a solid dielectric.
