sf6 emissions measurement tools

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.govHow Changes in Gas Temperature Affect Gas ... - WIKA Blog 15, 2016Circuit 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.
