A comparative study of field computation methods: Charge simulation method and method of moments

Abstract

Numerical methods plays a vital role in computation of electric fields for the design of high voltage systems. For electric fields studies related to high voltage applications, the preferred numerical methods are charge simulation method (CSM) and method of moments (MoM). In the present study, the performance of these two numerical methods are analyzed by simulating sphere-plane gap arrangement (which has an analytical solution to compare). Through this example, CSM is found to be more accurate compared to MoM. Further, the effect of change in sphere-plane gap geometry on the electric field computed is reported and discussed. � 2018 IEEE.
