Performance analysis of a saturated iron core superconducting fault current limiter using different core materials

In this paper, a study on various Fault Current Limiters, in particular the Saturated Iron-Core Type High-Temperature Superconducting Fault Current Limiter (SISFCL) has been carried out. The theoretical analysis of the Superconducting Fault Current Limiter has been accomplished using the Jiles-Atherton´s model of ferromagnetic hysteresis. The simulation of various responses, both electrical and magnetic, of a Saturated Core Superconducting Fault Current Limiter circuit has been realized using MATLAB Programming. Since the performance of the limiter depends on the characteristics of the core material, investigations have been carried out to study the response of the current limiter with three different core materials.
