CURRENT LIMITING ELEMENT AND CURRENT LIMITER

摘要

PROBLEM TO BE SOLVED: To provide current limiter of less AC loss and fast operation which comprises a superconducting-normalconducting transition type oxide bulk superconducting current limiting element. SOLUTION: There are provided at least a current limiting element, a mechanism to apply a magnetic field to the element, and a mechanism for adjusting the magnetic field component in a plate surface normal direction of a self magnetic field generated at the current limiting element and the direction of magnetic field component of the magnetic field applying mechanism.
