high-voltageswitchgear emissions detecting

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.govClimate change: Electrical industry's 'dirty secret ... › news › science-environment-49567197Sep 13, 2019It's the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years, the BBC has learned.

  • Modular Switchgear Monitoring (MSM)

    Based on the monitoring application, MSM is offered in 2 versions : MSM I is designed for SF6 gas monitoring allowing early detection and prevention of critical gas leakages in high-voltage switchgear, enabling to reduce SF6 gas emissions. MSM II enables circuit-breaker monitoring in addition to SF 6 gas monitoring, for improved operational reliability and performance of the circuit-breakers.
