Fighting global warming using sf 6 alternatives and AI - Seetalabs

May 18, 2020 · The gas insulated switchgear (GIS) is a popular example of sf6 gas application due to its higher dielectric strength, density, and electronegativity as compared to air. The self-healing of Sulfr hexafluoride also promotes its use for arc-quenching purposes. However, Sulfr hexafluoride is a green house gas with global warming potential (GWP) 24000 times higher than carbon dioxide. The life-cycle management costs while handling Sulfr hexafluoride-filled aged equipments is also high.
