Official abstract text for this publication.
A current-limiting device is a current-limiting device that uses a superconductor to perform a current-limiting operation, the current-limiting device including: a superconducting current-limiting element including the superconductor; a capacitor; a reactor; and a bypass switch. The series capacitor is connected in series to the superconducting current-limiting element. The current-limiting reactor is further connected in series to a series circuit including the superconducting current-limiting element and the series capacitor. The thyristor switch is connected in parallel to the series circuit.
