Insight into the compatibility between C4F7N and silver: Experiment and theory

Journal of Physics and Chemistry of Solids, 2019
Abstract Fluorinated nitrile (C4F7N) has received much attention as substitute gas for sulfur hexafluoride (SF6) using in electrical equipment over the past two years. In this paper, we explored the compatibility between C4F7N and silver theoretically and experimentally. The interaction mechanism between C4F7N and silver was investigated based on the

Experimental and Theoretical Exploration of C4F7N Gas Decomposition Under Partial Discharge

2020 IEEE International Conference on High Voltage Engineering and Application (ICHVE), 2020
SF 6 is widely used in high-voltage electrical equipment due to its excellent insulation and arc quenching ability. However, SF 6 is a greenhouse gas with a very high global warming potential (GWP), about 23,500 times than that of CO 2 . Recently, many studies have demonstrated that C 4 F 7 N has excellent insulation properties and environmental ...
