The European Union (EU) has released a report on the ...· Tighter regulation around SF6 in the energy industry is one of the expected outcomes. Even before the September 2020 report, the spotlight was already on SF6, for instance it is listed in the Kyoto Protocol. With a global warming potential (GWP) of 23,500, SF6 is considered the most potent of greenhouse gases.
SF6 Gas Insulated Equipment | Vaisala electric power industry uses SF6 to insulate switchgears, circuit breakers and other equipment used in electricity transmission and distribution. To ensure the integrity of SF6 gas as an insulator, the amount of water vapor in SF6 gas should be kept to a minimum.
