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

    Feb 14, 2012Opening 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 insulation138KV HLR ABB Breaker Fault Clearing TimeJun 08, 2017Fill Up or Top-up 132kV With SF6 GasJan 23, 2013Re-Baking of Low Hydrogen ElectrodesSep 20, 2010Maximum Acceptable Tan Delta Value of 132KV SF6 Circuit BreakerJul 04, 2010See more results

    SF6 gas has a high affinity of absorbing free electrons as its electro-negativity is very high. Moreover, SF6 is an excellent insulator. The SF6 molecules absorb the free electrons from the arc, and hence form a negative ion. These negatively charged ions have a very low mobility compared to the free electrons.
