Abstract:
To prepare a superconducting fault-current limiting element having a high sharing electric field at low cost, a superconducting fault-current limiting element includes an insulator substrate; a superconductive thin film formed on the insulator substrate; and an alloy layer formed on the superconducting thin film, said alloy layer having a room-temperature resistivity higher by twice or more than the room-temperature resistivity of a pure metal, in which, when the superconducting thin film goes into a normal conductive state by an overcurrent, the overcurrent flowing through the superconducting thin film is transferred only to the alloy layer.
