News Room : GE Grid Solutions

The standard gaz sf6 device was not suitable, so GE worked closely with gas equipment suppliers to develop a dedicated g3-filling cart. The key difference between g3 and gaz sf6 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
