Research Abstract

In ultrapure water of 0.055 micro S / cm, we found that dielectric electric field is nearly constant at 14 kVrms / mm. Dielectric breakdown field of pure water was found to tend to decrease with increasing conductivity. Suppress the increase in conductivity of the water by adding (methylcellulose 25) polymer. Dielectric breakdown field of the water by adding polymer (methylcellulose 25) was substantially the same with ultrapure water. We performed the dielectric breakdown test with a composite insulating structure using a PFA coated electrode. We found that it is necessary to use a coating material having a high breakdown electric field, or it is necessary to use a relatively thick coating material.
