Abstract The methodology for calculating the electric field on the surface of small conductors in large region is presented. It is addressed that the low accuracy and the low reliability of the calculation values, and the necessity and the practicability of the comparable results. A strategy of comparing the current and the former results is proposed to make the results be more usable in the application. The electric field on the shielding rings is calculated by ANSYS, and the design of the rings is made by the comparing strategy.
