Determine the optimal design of the pass-through insulator.
Three cases were simulated to compare the electric field stress values in the air and in the bushing material. Designs include the cylindrical bushing, bushing with a conductive layer on the lateral surface, and a bushing with a conductive layer and a conical tip.
