insulating gas gas in medium-voltage switchgear | TD Guardian Articles

sf6 gas has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses sf 6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

Thus, the data shows that the emissions from electrical transmission and distribution declined 79.9 percent from 1990 to 2013! The EPA report supports the opinion that emissions of SF 6 gas from modern designs of high-voltage and medium-voltage switchgear and circuit breakers is not a significant factor in global warming and climate change.

However, currently even best practices are self-imposed and not widespread due to scant legal obligation on SF 6 emissions. Since switchgear typically has a lifetime of 40-50 years, it is critical to act now. Eaton, along with many other industry voices, is calling for an immediate ban of SF 6 gas in medium voltage switchgear up to 36kV.

The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF 6 gas contained in its medium- and high-voltage switchgear. Uses in magnesium, aluminum, and electronics manufacturing also hastened atmospheric growth.

Myth About insulating gas Gas In Electrical Equipment

Where is gaz sf6 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 gaz sf6 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 sf6 gas 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 % (*).
