Sulfur Hexafluoride (sf 6) Basics | Electric Power Systems

Save Money - Purchasing SF 6 can be expensive, so reducing emissions can save money. Increase Grid Reliability - Use of improved SF 6 equipment and management practices helps protect system reliability and efficiency. Protect the Environment - SF 6 is the most potent greenhouse gas known. It is 22,800 times more effective at trapping infrared radiation than an equivalent amount of CO 2 and stays in the atmosphere for 3,200 years. Common Emission SourcesGet price

Electric Power Systems Partnership | Fluorinated Gas

Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for gaz 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 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 Sulfr hexafluoride-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of Sulfr hexafluoride, 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 insulating gascan impact the climate. The electric power industry uses roughly 80 percent of all gaz sf6 produced worldwide. Ideally, none of this gas would b...Get price
