Global Warming and the Necessity of SF6 Alternatives in SwitchgearWith the exacerbation of global warming, it becomes increasingly important to use alternatives to sulfur hexafluoride (SF6) in switchgear such as circuit breakers and Gas Insulated Switchgear (GIS) in the future. Fluoroketones and fluoronitriles are potential replacements due to their higher dielectric strength compared to SF6. However, these gases need to be mixed with a buffer gas for use at low temperatures; otherwise, they con
