SF6 Decomposition leakage and quality for HV MV

SF6 Decomposition leakage and quality for HV MV

SF6-alternative gases HV MV Equipment for railroad. Gas leakage IEC specifies an annual maximum sf6 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.
