BPA Puts Modernized Celilo Converter Station into Service ... Pacific Direct Current Intertie, a high-voltage direct current system (HVDC), was a marvel and a model when it was energized in 1970. Direct-current systems can move large amounts of electricity over long distances more efficiently than alternating current lines of a similar length because less power is lost to the air as heat along the way.

SF6 Solutions – GTR hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas, and an excellent electrical insulator.  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, it is poorly soluble in water but quite soluble in nonpolar organic solvents.
The Problem with Humidity in SF6 Gas-Insulated ... - WIKA blog hexafluoride is the gas most commonly used as insulator in power transmission and distribution switchgear. Water, however, can negatively affect the dielectric capabilities of SF 6 gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).
An alternative to SF6 in electrical switchgear - EE Publishers decades, the unique properties of sulfur hexafluoride (SF 6) have made it popular as an insulation and switching medium for electrical switchgear.However, SF 6 is a greenhouse gas and there are life-cycle management costs associated with its use.. For some years, ABB has been conducting research into alternatives with lower environmental impact but with insulation and arc interruption ...
Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
