IR SF6 check for leaks for Very High Voltages

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 custo…See more on epa.gov750a Refrigerant Leak DetectorTPI USA is toxic and emitted into the air when high voltage insulation begins to degrade.
