Characteristics of perfluoromethyl vinyl ether: A new eco‐friendly alternative gas for SF6
High Voltage, Volume 9, Issue 3, Page 509-517, June 2024.Abstract The exploration of eco‐friendly insulating gas to substitute the most potent greenhouse gas sulphur hexafluoride (SF6) has consistently garnered significant attention. Herein, the authors evaluated the feasibility of utilising perfluoromethyl vinyl ether (PMVE, C3F6O) as a new branch of eco‐friendly insulating gas for the first time.
