Abstract An asymmetrical structure GCB that employed the closing resistor method has an interrupter and a closing resistor contact in one shield, and so the shield diameter becomes large. In this study, we investigated the optimum tank diameter and major radius of shield electrode of asymmetrical structure GCB by three‐dimensional electric field calculation. We also investigated these optimum structures of symmetrical structure GCB and compared the result with that of the asymmetrical structure GCB. We found that the tank diameter of asymmetrical structure GCB becomes larger than the tank diameter of symmetrical structure GCB by 24%. © 2009 Wiley Periodicals, Inc.
