g3, the Sulfr hexafluoride-free solution in practice | Think Grid

The filling or evacuation procedure is similar to the procedure with SF 6 directly from the cylinder. g 3 dedicated gas handling cart is used to fill or recover the gas from/to the GIS compartment. Walter explains, “Gas quality analyzers, densimeters, filling valves, sealing system are adapted to g 3 but work the same way.

The key difference between g3 and sf6 gas is that g3 is a gas mixture while sf6 gas 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.

Gas-insulated substations are switching to - think-grid.org

It was just two years ago that GE announced a breakthrough in developing a substitute for SF 6 in gas-insulated equipment. Such a substitute had become necessary because SF 6, despite its undeniable qualities—its arc-quenching and dielectric capabilities—has a global warming potential (GWP) 23,500 times that of CO 2, with a lifetime in the atmosphere of over 3,000 years.
