Abstract
The scheme of a superconducting fault current limiter (SFCL) rated for operation in the DC electric networks at the maximum current of 300 A, is proposed. This device incorporates a module based on 2G high-temperature superconductors and a quick-action vacuum DC interrupter. Authors present the investigation results relating both to the current-limiting capacity of DC SFCL and to recovery time of the super-conducting state after current disconnection at the voltage of 3.5 kV.
