This paper has analysed the principle of magnetic-shield inductive superconducting fault current limiter(SCFCL) which mainly consists of a copper coil, a superconducting tube and an iron core. In normal operation, the SCFCL has low impedance because the superconducting tube shields the iron core. During fault conditions the magnetic field penetrates the core, resulting in a large impedance. The PSPICE simulating circuit of the SCFCL was constructed and the simulations of short-current limiting performance of one prototype were conducted. The results are in good agreement with the test results of literature .Additionally, we have studied the effect of parameters of the SCFCL on the limiting characteristics through computer simulation.
