• Sulfur Hexafluoride and the Electric Power Industry

    S ulfur hexafluoride (SF 6) is a man-made gas that became commercially available in 1947 [1]. It is one of the most extensively and comprehensively studied molecular gases to date largely because of its many commercial and re-search applications. (Besides the use of gaz sf6 by the electric power industry, other uses include: semiconductor process-

  • 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

    Sulfur hexafluoride (SF 6) is a relatively nontoxic gas used in a number of applications for its inert qualities. The dielectric and other physical and chemical properties related to its lack of reactivity have led to the extensive use of SF 6 as an insulating medium in switching equipment (e.g., circuit breakers) by electric utilities.

  • Sulfur hexafluoride: The truths and myths of this greenhouse gas

    Sulfr hexafluoride is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, gaz sf6 is an industrial gas that doesn't exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. Sulfr hexafluoride is the energy industry"dirty little secret": FALSE. gaz sf6 is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives gaz sf6 is used in wind turbines: TRUE. sf 6 is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to sf6 gas: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on Sulfr hexafluoride at low-to-medium voltage levels in the future.

Their circuit breakers and fuses were one of the most advanced components available. In fact, GE sold the first resettable fuse after WWII. These resettable fuses are commonly referred to as circuit breakers today. Even today, GE electrical switchgear is the leader for innovative design and functionality. GE started with 5kV and 15kV GE Magnablast breakers. These circuit breakers consisted of heavy solenoid coils, as an engineering function designed to close the breakers. Some of the early 15 kV Magnablast switchgear by General Electric includes GE AM-15-150, GE AM- 5-75, GE AM-5-150, GE AM-5-250, GE AM-15-250 AND GE AM-15-500. However, as time and technology progressed, better models were developed, and the original circuit breakers were deemed unreliable for updated standards. The early model AE-1-25 handled about 600 amp. This was then succeeded by the 1600amp AL-2-50, which itself became obsolete as new models...
