insulating gas circuit breaker maintenance | TD Guardian Articles

The first generation of insulating gas circuit breakers was the lower voltage classes of 72kV and 145kV. As insulating gas 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 sf6 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 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.
