sf 6 circuit breaker maintenance | TD Guardian Articles

The first generation of sf6 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 sf 6 as the line-to ground dielectric insulation.

Opening of 132kV Breaker with Very Low sf 6 Pressure - CR4

Opening a completely isolated Sulfr hexafluoride breaker with very little or no gaz sf6 gas (as if it were in a testing lab) would pose no threat to the health of the breaker. There is no auto-trip feature. I think auto-trip at such low gas pressure may not be desirable because arcing might start across the open contacts of breaker due to very less insulation
