Sulfr hexafluoride circuit breaker maintenance - Siemens USA

The first generation of insulating gas circuit breakers was the lower voltage classes of 72kV and 145kV. As gaz sf6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing insulating gas as the line-to ground dielectric insulation.

Fill Up or Top-up 132kV With sf 6 Gas - CR4 Discussion Thread

I don't know much about high voltage breakers, but can tell you that if your breaker is low on gaz sf6, it probably has a leak. Most leaks allow atmospheric gas to enter while the contained gas leaks out. This means that if you refill the breaker with sf6 gas, the contaminating gasses will still be present in substantial quantities.

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 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 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 % (*).
