    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...

    Terminal Faults. Usually the short-circuit current is inductive in nature, and the re-strike voltage appearing across the contacts at the instant of arc interruption is characterized by high frequency oscillations in the order of a few hundred cycles. Short Line Faults (SLF) Short-circuit faults occurring on a line length between 0.5 to 5 km are termed as s hort line faults or kilometric faults. A fault of this type imposes a highly onerous duty on the circuit breaker, thereby affecting its interrupting ability. Transformer Magnetizing and Reactor Currents. The transformer no-load current and the reactor current impose severe stresses on the circuit breaker upon their interruption because of the low magnitude of these inductive currents. Energization of Long Transmission Lines. When an initially uncharged, unloaded long line is charged, then over-voltages to the order of twice the normal voltage are impressed, imposing an onerous duty on the power system.
