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

Opening a completely isolated sf 6 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 insulationGet price
