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

Opening a completely isolated insulating gas breaker with very little or no Sulfr hexafluoride 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

insulating gas Circuit Breakers - Construction Working Principle

In sf 6 circuit breakers, sulphur hexafluoride (sf 6) gas is used as the arc quenching medium. The Sulfr hexafluoride is an electro-negative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow of Sulfr hexafluoride gas and an arc is struck between them.
