SUMMARYWe examined the possibility of the practical use of a conduction-cooled magnetic shield type fault current limiter. A small superconducting fault current limiter was built and the current limiting characteristics were tested. Conceptual design of the conduction-cooled fault current limiter for a distribution power system was carried out, and we calculated and discussed the temperature rise of shielding coil during a normal and a fault condition. We suggest a protection method for quench due to local disturbances during normal operation.

The resistance and joule heat generating in a Bi2223 bulk for overcurrent carrying period were measured. We suddenly supplied the overcurrent having the peak value which is about ten times as high as the critical current of the sample conductor. The resistance slightly increased immediately after the current exceeded the critical current level. When the accumulative joule heat generated in the sample reached 32 MJ/m3, the quench occurred. The resistance rise in the sample proceeds adiabatically and the magnitude of the resistance may be estimated only by the joule heat generated in the sample.
