Abstract

An analysis of electric fields in dielectrics plays a very important role to design an insulation capacity of electrical machineries and to clarify a mechanism of dielectric breakdown. Especially, it is expected that the direct observation of continuously changing electric fields of them give tremendous contributions to insulation design. The anthers have been studied to analyze and simulate some types of electric fields by a fluid flow mapper which is an equipment of fluid flow visualization. This paper visualizes and analyzes electric fields on spherical shape voids occurred within dielectrics put into a parallel plate electrodes by means of the fluid flow mapper method. Finally, the graphical results from flow patterns of the complex dielectic system are compared and examined to appreciate the justification of this method applying to this system by the analytical and the numerical results of it's electric fields.
