Myth About Sulfr hexafluoride Gas In Electrical Equipment

Where is sf6 gas used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is sf6 gas a health hazard? Pure Sulfr hexafluoride is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is Sulfr hexafluoride harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of gaz sf6 used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).

Electric Power Systems Partnership | Fluorinated Gas

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 Sulfr hexafluoride emissions from electric power systems, such as the type and age of the gaz sf6-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 Sulfr hexafluoridecan impact the climate. The electric power industry uses roughly 80 percent of all insulating gas produced worldwide. Ideally, none of this gas would b...Get price
