SF6 decomposition leakage for HV MV

SF6 decomposition leakage for HV MV

SF6-alternative gases HV MV Equipment for railroad. Gas leakage IEC specifies an annual maximum SF 6 leakage rate of 0.5 % or 1 %. Experience from several high and low temperature tests and decades of operational experience show that the leakage rate of Siemens circuit breakers is below 0.1 % per year.

  • Myth About SF6 Gas In Electrical Equipment

    2020-5-253. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
