  • The effect of electrode surface roughness on the breakdown

    Jun 01, 2020 · C 3 F 7 CN/CO 2 gas mixtures have been widely studied in recent years. And they are considered a potential alternative for replacing SF 6 in high voltage power equipment. In this paper, the DC breakdown characteristics of 6%C 3 F 7 CN/94%CO 2 mixtures in a uniform electric field were studied at electrode surface roughness levels of 0.4 μm, 1.2 μm, 2.1 μm and 3.8 μm.
