for 2 hours at -50oC and the circuit breaker operated). 2.2 Mixed Gas At low ambient temperatures, below -30oC or -40oC (depending on filling pressure), there is a risk of sf6-gas condensation, which can cause some reduction of breaking capacity. To avoid this, circuit breakers can be filled with a gas mixture of sf 6 and N 2 or sf 6 and CF 4.

  • Opening of 132kV Breaker with Very Low SF6 Pressure - CR4

    Opening a completely isolated SF6 breaker with very little or no 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
