#### Abstract

In this paper, the electric field distribution in dielectric tube with one layer and spherical dielectric in water was simulated. The reactor was made up of the spherical dielectric that is diameter 2.5[mm], ${\epsilon}_r$ : 5, 100, 1000, 5000 respectively and one glass plate being 2[mm] thickness, ${\epsilon}_r$ : 5 as electrode. The discharge gap was 7[mm]. As a result of the simulation, in case of being about the same value between the dielectric constant of spherical dielectric and water, when the reactor was applied to high voltage dielectric polarization characteristic was trending toward disappearance. To get more strong electric field, the dielectric constant should be higher comparatively, Increasing the spherical dielectric constant, the location of equippotential line was shifting from the interior to the exterior.
