Arc motion and gas flow in current limiting circuit breakers operating with a low contact switching velocity [PDF]

open access: yes, 2002
Arc motion in low voltage (240 VAC) high current (10/sup 3/-10/sup 4/A.) current limiting-circuit breakers is dominated by arc root mobility. The mobility is influenced by the gas flow and gas composition in the contact region, but there is little ...
