Superconducting fault current limiters (SFCL) use the natural ability of rapid shifting from the normal to the resistive state of superconductor due to their critical current value exciding. This special feature of superconducting materials enables designing of electrical devices with parameters that cannot be achieved by using conventional materials. The voltage dependence on the structure of superconducting inductive fault current limiter in a superconducting state has been described in this paper. This dependence has enabled elaboration of computer software for parameters optimizations of SFCL primary winding. This dependence in a resistive state is also described. The analysis was carried out using FLUX2D software based on a finite element method.
