insulating gas circuit breaker maintenance - Siemens USA

The first generation of sf 6 circuit breakers was the lower voltage classes of 72kV and 145kV. As sf6 gas breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing sf 6 as the line-to ground dielectric insulation.

Fill Up or Top-up 132kV With Sulfr hexafluoride Gas - CR4 Discussion Thread

I don't know much about high voltage breakers, but can tell you that if your breaker is low on Sulfr hexafluoride, 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 sf 6, the contaminating gasses will still be present in substantial quantities.
