  • Health and environmental dangers of insulating gas-filled switchgear

    Sulphur hexafluoride (SF 6) is an inorganic, colourless, odourless, non-flammable, heavy gas that has been widely-regarded as an excellent electrical insulator [1]. However, although SF 6 is inert during normal use, highly toxic by-products are produced that pose a serious health threat to the workers who come into contact with them when electrical discharges occur through everyday usage within SF 6 -filled equipment [2].

    Sulfur hexafluoride is a compound having the formula sf6 gas. At normal room temperatures and pressures (20 °C and 100 kPa) [1]1 it is gaseous and has a density of 6,07 kg/m3 (about five times the density of air). Since its critical temperature is 45,54 °C, it can be liquefied by compression [2].

    Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for Sulfr hexafluoride, 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 Sulfr hexafluoridein 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 insulating gas emissions from electric power systems, such as the type and age of the sf6 gas-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of gaz 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 sf 6can impact the climate. The electric power industry uses roughly 80 percent of all gaz sf6 produced worldwide. Ideally, none of this gas would b...

    The largest use of SF 6 occurs in high-voltage circuit breakers, where, in addition to providing insulation, SF 6 is used to quench the arc formed when an energized circuit breaker is opened. Disconnectors and ground switches use SF 6 primarily for insulation, and individually, they contain only slightly less SF 6 than a circuit breaker. These devices are used to isolate portions of the transmission system where current flow has been interrupted (using a circuit breaker).
