Abstract

This paper explained electric field distribution's characteristics of dielectric pellets with a shape of ball to voltage. When discharge gap of electrode and input voltage are each 20[mm], 10000[V], the electric field simulation results of dielectric pellets with a shape of ball with relative dielectric constant of several kind measured stronger electric field near electric pellets with a shape of ball of ${\phi}5$[mm] than $1{\phi}$[mm] and $3.33{\phi}$[mm] at atmosphere. And the maximum electric field of dielectric pellets with a shape of ball over ${\phi}5$[mm] increased about 5[%] to maximum electric field of electric pellets with a shape of ball ${\phi}5$[mm]. And the result of simulation, when relative dielectric constant of dielectric pellets with a shape of ball is 100, it measured about 90[%] of maximum electric field of dielectric pellets with a shape of ball with relative dielectric constant over 1000.
