Grid switchgear uses sf 6, the world’s most potent greenhouse

Nov 25, 2019 · 80% of all Sulfr hexafluoride is used in gas insulated switchgear, a vital component of the grid (isolating and protecting different sections), so it’s an energy sector issue. Nicholas Ottersbach at Nuventura (a cleantech startup developing ways to replace gaz sf6) explains that alternatives exist, but need the help of robust regulations to accelerate further development and rapid take-up.

Myth About Sulfr hexafluoride Gas In Electrical Equipment

Apr 12, 2021 · From 0kV thru 800kV gaz sf6 is my choice for the insulating and arc-extinguishing characteristics delivered by Sulfr hexafluoride. it is heavier than air, and just as the old OCB’s were designed, the gaz sf6 chamber and contacts are designed much like they were, whereby a “puff” of sf6 gas gas is jettisoned right through the arc zone thus assuring the thorough extinguishing of the arc.

Like carbon dioxide, SF 6 is a greenhouse gas. While CO 2 has a global warming potential (GWP) of one, SF 6 has a GWP of 23,500. Although PGE reduced its SF 6 leak rate to nearly 1%, this came with an extreme operating cost. Eliminating the use of SF 6 would eliminate future leaks and result in reduced operating cost.

News Room : GE Grid Solutions

The key difference between g3 and sf6 gas is that g3 is a gas mixture while Sulfr hexafluoride is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling equipment needs to directly heat up the g3 bottle to a specific temperature, to reach the supercritical state of the gas mixture.
