The concentrations of CO2, CF4, thionyl sulfide (SOF2), sulfuryl fluoride (SO2F2), disulfuryl decafluoride (S2OF10), sulfur dioxide (SO2) and sulfureted hydrogen (H2S) were in partial normal distribution. The concentrations of CO2, CF4, SOF2, SO2F2, S2OF10 were all below 0.1%; the concentrations of SO2 were below 3μL/L; the concentrations of H2S were below 1μL/L. The SF6 byproducts concentrations in 500kV GIS were lower than those in 220kV GIS. The SF6 byproducts concentrations were lower in GIS that have been operating longer. The SF6 byproducts concentrations were significantly different in equipment from different manufacturers.
