Sulfur hexafluoride - Wikipedia

6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen. The high dielectric strength is a result of the gashigh electronegativity and density. This property makes it possible to significantly reduce the size of electrical gear.Get price

How Ambient Conditions Can Compromise Density Measurements in

Dec 13, 2016 · Absolute pressure uses a vacuum as reference, while relative pressure uses ambient pressure as reference. By being referenced to a vacuum, absolute pressure eliminates any inaccuracies that can be caused by changes in ambient pressure. The actual gas pressure is accurately measured, leading to correctly calculated gas density.Get price
