Abstract: The present invention relates to a superconducting fault current limiter which has a contact point switch and uses magnetic composition. The superconducting fault current limiter which has the contact point switch and uses the magnetic composition according to an embodiment of the present invention comprises; a primary side wire in which one end is connected to an input terminal; a secondary side wire in which one end is connected to the input terminal and the one end of the primary side terminal; a superconductor in which one end is connected to the other end of the secondary side wire; and a contact point switch in which one end is connected to the other end of the superconductor and the other end is connected to the other end of the primary side wire and an output terminal. The primary side terminal is wound up a core. The secondary side terminal is wound up the core. The contact point switch is turned on or off according to the size of a current which is inserted from the input terminal. Therefore, performance deterioration is prevented by separating superconductor from a failure current using the contact point switch if the failure current is inserted into the superconducting fault current limiter.

The overcurrent relay in consideration of application of a superconducting fault current limiter according to one embodiment of the present invention comprises: a current measuring unit for measuring a current at a contact point between the superconducting fault current limiter and a circuit breaker that are sequentially connected between a distribution line connected to a transformer and a load; a voltage measuring unit for measuring a voltage at a contact point between the superconducting fault current limiter and the circuit breaker; and a setting unit for setting an operation of the circuit breaker using a fault current and a fault voltage that are measured at the contact point when a fault occurs between the distribution line and the load. Therefore, when a superconducting fault current limiter is added to a power system, an overcurrent relay compensates fault current components decreased by the superconducting current limiter, whereby protection coordination of protective devices can be achieved.
