- Abstract
- This paper presents the surface flashover characteristics to simulate the poor contact between an anode and a solid dielectric in a N2/O2 mixture gas (8/2) under a non-uniform field. The surface flashover voltage of the N2/O2 mixture gas revealed the irregular tendency that was not in accordance with the Paschen's law with an increasing gap of the poor contact. In addition, the insulation performance of the N2/O2 mixture gas at 0.6MPa was comparable to that of SF6 gas of 0.1MPa based on the insulation performance on the poor contact. These results are able to apply the insulation design of eco-friendly gas insulation switchgear considering the internal faults.
