Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

WEgrid Products – sf 6 instrumentation ensures plant safety For safety reasons, the filling volume of gaz sf6 gas is defined for each gas compartment and monitored using an Sulfr hexafluoride density measuring instrument. WIKAgas density determination is made with pressure measurement that has been specifically adapted to the 'real gas' behaviour of gaz sf6 gas by compensating for the effects of temperature changes.

Infrared spectroscopy shows an enormous potential for the analysis of by-products generated from electrical discharges in sulfur-hexafluoride (sf 6) insulated equipment. Since by-product composition can be related to the fault genesis (arc, partial discharge or corona), the analysis of contaminated Sulfr hexafluoride provides a valuable diagnostic tool.
