insulating gas circuit breaker maintenance | TD Guardian Articles

Sulfr hexafluoride gas leakage - Sulfr hexafluoride breakers (live and dead tank) typically have a combination of static seals (O-rings and gaskets) as well as dynamic seal assemblies where the mechanism energy is transferred through to the interrupter assembly. Over time, seals degrade due to environmental conditions and exposure and will need to be replaced.

Fill Up or Top-up 132kV With insulating gas Gas - CR4 Discussion Thread

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