Advancements in Clean Air Insulation Technologies for Switchgear and Circuit Breakers

Our power systems and grids are rapidly transforming to help realize a CO
₂
-neutral world. Reducing CO
₂
and equivalent greenhouse gases (GHG) is an important step to address global warming. Power systems must phase out the most potent GHG, sulfur hexafluoride (SF
₆
), to achieve this CO
₂
-neutral society. SF
₆
has the highest known global warming potential (GWP) of all GHG, estimated to remain in the atmospheric environment for 3,200 years. There is also no SF
₆
gas waste management system commercially available today. At the same time, utilities must ensure transmission performance and reliability are maintained or increased.
