  • Industrial SF6 Gas Pressure and Measurement Products - WIKA USA

    Although sulfur hexafluoride is nontoxic and nonflammable, escaped gas in enclosed rooms displaces oxygen in the air and could lead to asphyxiation. SF 6 is also a potent greenhouse gas – 23,900 times more effective than carbon dioxide at trapping infrared radiation in the atmosphere. In addition, TD plant safety depends on the purity of SF 6 gas. Under normal conditions during an electrical discharge, the six fluorine atoms split from the sulfur atom to capture electrons; after quenching

  • 15 FAQs about SF6 Gas and SF6 Breakers - WIKA blog

    What is SF6 gas? Sulfur hexafluoride is an octahedral (eight faces and six vertices) molecule. It consists of six fluorine atoms surrounding a sulfur atom. What are the characteristics of SF6 gas? SF6 is colorless, odorless, nonflammable, and nontoxic. It is virtually inert, which means it is stable and does not react with other chemicals under normal conditions. Why is SF6 gas such a good dielectric medium? First, dielectricity is the ability to transmit electricity without conductivity, and dielectric strength refers to how well something can withstand high voltage without breaking down. What is the importance of arc quenching in T&D equipment? When switching or opening an electrical circuit that deals with more than 250 volts, as the contacts start to open, an arc forms between them.

    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 of the SF6-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of SF6, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of SF6can impact the climate. The electric power industry uses roughly 80 percent of all SF6 produced worldwide. Ideally, none of this gas would b...
