Abstract: 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 ...
Abstract: The operation of HVdc grids faces two critical challenges: 1) fast interruption of dc-side fault currents and 2) power flow management to prevent dc lines from overloading in some scenarios.
