Alternative insulation gas for medium-voltage switchgear ...· Abstract: Although the contribution of SF6 (sulfur hexafluoride) emissions from gas insulated medium-voltage switchgear to man-made global warming is very small, an eco-efficient insulation gas will contribute to a reduction in the carbon footprint of the electricity grid. Based on fluoroketone molecules an alternative to SF6 gas insulation has been developed for medium-voltage switchgear applications.
