  • SF6 Monitoring System for GIS – GE Grid Solutions

    SF 6 Monitoring System for GIS. With worldwide scrutiny on SF 6 gas usage, increased environmental reporting requirements and even possible penalties, precise early detection of small gas leaks in Gas Insulated Substations that use so much SF 6 is essential. The B Watch uses the latest generation of EMC resistant digital gas sensors to continuously measure gas pressure and temperatures in order to track changes in density and detect gas leaks down to 0.1% per year.

  • 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.

    The cordless battery-operated LEAKSPY SF6 precisely measures SF 6 concentration in air by means of a non dispersive infrared sensor (NDIR sensor) and indicates the value on a graphic display in ppm v. The device allows precise localisation of leaks by searching the highest SF 6 concentration. Thanks to the high accuracy and the low detection limit it is possible to carry out integral measurements as well as measurements for determination of leakage rates.

  • g3, the SF6-free solution in practice | Think Grid

    When applied in the GIS, the GWP of the gas is even more reduced and brought down to more than 99% simply because the necessary gas mass of g 3 for one bay is half the necessary mass of SF 6. The g 3-GIS yields a 15% increased impact on ozone depletion. The latest is due to the greater use of polytetrafluoroethylene (PTFE) material in the circuit breaker to cope with the characteristics of the alternative gas; However, since PTFE quantities are very low, this increase is negligibly small

    It was just two years ago that GE announced a breakthrough in developing a substitute for SF6 in gas-insulated equipment. Such a substitute had become necessary because SF6, despite its undeniable qualities—its arc-quenching and dielectric capabilities—has a global warming potential (GWP) 23,500 times that of CO2, with a lifetime in the atmosphere of over 3,000 years.
