Abstract
The superconducting fault current limiter is expected to be the first application of high-TC superconductors to electric power systems. To analyze the performance of the magnetic shielding-type superconducting fault current limiter, the dependence of the voltage-current (E-J) characteristics of high-TC superconducting bulk on temperature and magnetic field have been measured. Short-circuit fault tests with a small limiter model have been carried out. A computer program based on the finite element method was used for evaluation of the dynamic electromagnetic behavior of the HTS cylinder in a time-varying external magnetic field. The computer program, considering the voltage-current (E-J) characteristic, successfully simulated the electromagnetic behavior in the fault current limiter test.
