Electric field relaxing electrodes design using particle swarm optimization and finite elements method

Abstract

In this paper, a methodology for design of electrical field relaxing electrodes is shown. This design methodology is based in an optimization process carried out by particle swarm optimization technique. The objective function of the optimization process, include the electro statics model of the high voltage equipment that is solved by the finite element method. The proposed methodology was implemented using the computational tools Matlab and Comsol. This methodology was validated by designing the electric fields relaxing electrodes in a high voltage resistive divider, which used in measurement of lightning impulse waves.
