tif IR SF6 Density Monitors for proper equipment

Dec 15, 2016 · How Changes in Gas Temperature Affect Gas Density Measurements. Circuit breakers, disconnectors, and switchgear in power transmission and distribution (TD) operations have been using sulfur hexafluoride (SF 6) as insulation for decades. To maintain the excellent thermal conductivity and dielectric strength of SF 6, however, you must keep proper amounts of SF 6, gas purity and minimize the amounts of humidity and byproducts inside the gas chamber.
