Simulation of Electric Field Effects in High Voltage Insulation Material Containing Air Voids

This study presents the simulation of the electrical field distribution in voids encapsulated in epoxy insulation material using QuickField™ software. The significance of this study is to further understand how electric field distribution influences partial discharge activity in insulation material containing air voids. The insulation model consists of single and double voids located in the middle of the insulation. The simulation results indicate that the electric field in the single void is higher than in the case of two voids adjacent to each other. However, despite the voids being identical to the enhancements of the electric fields in the voids is not to the same extent.
