Zero emissions SF6 N2 Mixtures emissions

In order to comply with this aim, one of the solutions adopted by the manufacturers and the users of some of these equipments, consists in reducing the quantity of SF 6 used by mixing it with zero (or very much lower) risk gases.For instance, as SF 6 /N 2 mixtures with SF 6 concentrations lying between 5 and 15% realise a satisfactory compromise between dielectric performances and cost, Electricité de France plans to use these mixtures to fill its future gas-insulated lines 2.

  • SF6: The Truths and Myths of this Greenhouse Gas

    SF6 is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, SF6 is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. SF6 is the energy industry’s “dirty little secret”: FALSE. SF6 is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives SF6 is used in wind turbines: TRUE. SF6 is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to SF6: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on SF6 at low-to-medium voltage levels in the future.
