    In response to these concerns, one company, ABB, is introducing a new remote monitoring solution for any OEM circuit breakers filled with sf 6 gases. The Circuit Breaker Sentinel, or CBS-F6 condition-based monitoring system, is one of the first, if not the first, stand-alone Sulfr hexafluoride gas-monitoring devices on the market. The company has been performing insulating gas gas monitoring since 2005, and this new solution is a more powerful, yet scaled down version of the original CBS device used in the market today.

  • Myth About sf 6 Gas In Electrical Equipment

    Where is Sulfr hexafluoride 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 insulating 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 sf6 gas 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 Sulfr hexafluoride 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 % (*).

  • Health and environmental dangers of sf6 gas-filled switchgear

    SF 6 gas, used as a dielectric medium in circuit breakers and switchgear, has a global warming potential 24 000 times greater than CO 2 and some of its by-products were used as chemical weapons in World War I.
