SF6 handling Charging GE

The sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (SF6) gas and an arc is struck between them. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions.

  • Green Gas for Grid - g3 - SF6 Free - GE Grid 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.

    In SF6 circuit breakers, the same principle is employed, with SF6 as the medium instead of air. In the “puffer” SF6 breaker, the motion of the contacts compresses the gas and forces it to flow through an orifice into the neighborhood of the arc. Both types of SF6 breakers have been developed for EHV (extra high voltage) transmission systems.
