Abstract
This paper studied surface discharge characteristics by a dielectric constant and diameter of solid dielectrics in N2/O2 mixture gas. Applied electric field strength at N2/O2 mixture gas was changed from the dielectric constant and diameter of the solid dielectrics, and insulation performance of the N2/O2 mixture gas determined surface discharge voltage. In each of the diameter at the solid dielectrics, the surface discharge voltage was increased by lengthening surface distance, whereas increasing rate of the surface discharge voltage was different from gas pressure. Thus, In this paper, main factors of surface discharge are as follows. 1) Insulation performance of N2/O2 mixture gas, 2) Dielectric constant of solid dielectrics, 3) Surface discharge path. It was clear that the surface discharge voltage depend on the main factors. These results will be applied to useful data for an eco-friendly composite insulation design.
