  • Green Gas for Grid - g3 - SF6 Free Solutions

    SF 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 SF6 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.What is GE’s g3?g³, (pronounced g cubed) is GEs game-changing alternative to SF6 gas, developed for HV electrical transmission equipment.Is there an alternative gas to SF6 for HV equipment?Yes, there is GE’s green gas for grids, g3 pronounced gcubed that is GEs game-changing alternative to SF6 gas, developed for HV electrical transmi...Can I replace SF6 by g3 in existing HV equipment?Direct retrofit is not possible.

  • Alternatives for SF6 | 2020 | Siemens Energy Global

    Most prominent among available options are “clean air” solutions, i.e. purified air, and gas mixtures that both have a fraction of the climate impact of SF 6. Hermetically sealed systems with clean air as an insulating gas take up more space than SF 6 , but combined with digitalised current and voltage transformers these systems can be built as small as current SF 6 systems.

    The key difference between g3 and SF6 is that g3 is a gas mixture while SF6 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
