Abstract
Our power systems and grids are rapidly transforming to help realize a CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> -neutral world. Reducing CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> 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 <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sub> ), to achieve this CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> -neutral society. SF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sub> 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 <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sub> gas waste management system commercially available today. At the same time, utilities must ensure transmission performance and reliability are maintained or increased.
