sf 6 dew point cost

However, it should be noted that for the SF6 gas to effectively serve its functions, it has to be of high quality. At the filling stage, a sample of gas is drawn from each chamber of the switchgear and tested for purity (% of SF6 gas), dew point (moisture content) and SO2 (signs of partial discharge).
