For the design of 20 kV cable accessories, a stress-cone with semi conductive ZnO microvaristors is examined using finite element method (FEM) simulations. It is virtually prototyped for various geometric design parameters and benchmarked by applying a test voltage. Based on the results, an optimal design is chosen and compared to standard cable accessories in virtual and experimental lightning surge tests in a high voltage laboratory.
