Electric Field Calculation for Vacuum Interrupter by Optimized Charge Simulation Method

In the charge simulation method (CSM), the determination of simulated charges in electrode depends, to a great extent, on the experience of calculators. Meanwhile, the problem is encountered in arranging the simulated charges in the thin electrode. Many investigators have been dedicating for solving these problems, one of the better way is using optimization strategy. Due to the optimized variables are so large that it will turn the optimization unworkable. In this paper, the method of selecting a proper function to determine the coordinate of simulated charges is proposed which makes optimized variables much reduced. In addition, the boundary displacement technique is proposed which brings the thin electrode problem well resolved
