Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for SF6, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950's, the U.S. electric power industry has used SF6in circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect SF6 emissions from electric power systems, such as the type and age o…See more on epa.govOem Voc Solution For Sale To Relations.

  • Ultra-Trace Analysis Technique for SF6 Using Gas

    Abstract. Sulfur hexafluoride (SF 6) is widely used as a tracer gas because of its detectability at low concentrations.This attribute of SF 6 allows the quantification of both small-scale flows, such as leakage, and large-scale flows, such as atmospheric currents. SF 6 s high detection sensitivity also facilitates greater usage efficiency and lower operating cost for tracer deployments by
