SF6 Gas Analysis for GI Switchgear - Qrometric Insulated Switchgear. For SF6 filled gas compartments, SF6 in accordance with either IEC 60376 or IEC 60480 is used. In order to prevent condensation, the maximum allowable water content is defined by a dew-point no higher than – 5 °C. Gas compartment fill specifications typically define much lower dew points (manufacturer dependent).

Gas density monitors - Product overview - WIKA United Kingdom 6 gas density monitors: reliable warning against low gas quantities . Sulfur hexafluoride (SF 6) is an extremely effective electrical insulator for medium- and high-voltage switchgear.For proper insulation, gas density must remain within certain levels. Furthermore, as SF 6 is a potent greenhouse gas, it must not escape into the atmosphere. An SF 6 gas density monitor warns operators of ...
