Can Epoxy Resin Insulators Reduce Corona Loss?

From the perspective of charge accumulation behavior at the gas-solid interface, under high-voltage DC or AC environments, surface charge accumulation on the high voltage epoxy resin surface can lead to local electric field distortion, surface discharge, and even flashover. Modifying the high voltage standoff surface can accelerate the dissipation of surface charge. Therefore, by controlling the distribution and accumulation of interface charge, the probability of corona discharge can be affected to a certain extent, thereby influencing corona loss.
