Abstract

The paper presents field stress control for a cylindrical spacer placed between plane electrodes appropriately profiled. The method analyzed utilizes varied angle between the electrode and the surface of the insulator. Computer simulation of the electrical field distribution was preformed. Mechanisms of flashover and voltage holdoff capability for an investigated vacuum insulating system are discussed. The method of estimating the critical electric strength of a system is proposed. The calculated results are compared to the experimental results obtained for real vacuum insulating systems. Varying the electrode angle was found as an efficient technique for field stress control
