• g3 - GE Grid Solutions

    SF 6 sf 6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 insulating gas is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

    The key difference between g3 and gaz sf6 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. 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.

    Nov 17, 2011 · However when there is a leakage and air enters the Sulfr hexafluoride gas compartment, it will bring along the moisture. Air and moisture will prevent the Sulfur atom and Fluorine molecule to combine back. In immense heat, highly mobile hydrogen molecules will combine with Fluorine molecule and form Hydrogen Fluoride which is corrosive in nature.
