Abstract

This paper deals with theoretical prediction of the quench behavior for a superconducting fault current limiter (SFCL) module. The SFCL module consists of a monofilar type BSCCO-2212 bulk and a shunt coil made of copper or brass. The BSCCO-2212 bulk coil is placed inside the shunt coil, and they are connected in parallel. In order to analyse the quench behavior of the module, the equivalent circuit equation was first derived from the experimental circuit structure and then the partial differential equation was solved. The inductance values of the BSCCO bulk coil and impedance of the shunt coil are calculated by Bio-Savart and Ohm's formula, respectively. We computed the voltage and current behavior during quenches using those values, and compared the results with experimental short-circuit data for the SFCL module. Both computation and test results agreed well. Therefore, we conclude that the analytic result can be applied effectively to design of a SFCL module.
