Abstract

This paper introduces a new design solution for the high-power superconducting fault current limiter (SFCL). The device consists of concentric sections with a circular cross-section shape which are connected in series in such a way that the current in adjacent sections flows in mutually opposite directions. The analysis of efficiency of various designs and optimization of their geometry and dimensions was performed through numerical simulations. They show that the higher number of sections gives the ability to substantially decrease the amount of superconducting materials and to reduce hysteresis losses.
