- Abstract
- The insulation design of high-voltage equipment is based on physical information about surface discharge mechanism. However, few studies have provided the information. This paper presents a peculiar-surface discharge characteristic in the presence of particle around an epoxy surface. Surface discharge experiments were conducted to measure partial discharge (V-P) and surface flashover voltage (V-F) with particle locations from the epoxy surface in atmospheric air. There was no the significant change in V-P on the particle location. In contrast, V-F revealed the distinctive-insulation characteristic that showed its peak. This characteristic was described from the space charge and the proposed surface discharge mechanism.
