Properties comparison of superconducting fault current limiters with closed and open core

Recently, the high-T-c superconducting fault current limiter (SFCL) has been studied worldwide to be classified into a resistive, inductive and hybrid type. HTSFCL of an inductive type seems to be the most prospective due to the simple design (construction) of the secondary superconducting winding in the form of the ceramic type made of BSCCO and for the reduction of current leads. In the inductive type of SFCL, ferromagnetic cores for magnetic flux are applied, however open cores are also taken into consideration that make the construction more simple. The results of experimental and computational investigation of the inductive SFCL parameters have been presented in the paper.
