Study of a SFCL Equipped with a Vacuum Interrupter Driven by Electromagnetic Repulsion Force for High-voltage SFCLs

TEION KOGAKU (Journal of the Cryogenic Society of Japan), 2007
Using a high-temperature superconductor, we constructed and tested a model superconducting fault current limiter (SFCL). The superconductor and vacuum interrupter as the commutation switch were connected in parallel using a bypass coil. When the fault current flows in this equipment, the superconductor is quenched and the current is then transferred to
