I. Introduction
Superconducting fault current limiters (SFCL) are one of the most promising device as an effective solution to reduce the increasing fault current level in power transmission networks where the prospective fault current level is becoming higher than the capacity of the circuit breakers. The SFCL using low temperature superconductors (LTS) had been studied in two conceptual designs: the resistive and the inductive ones [1]. However, due to high cooling costs for operation at 4.2 K they have not achieved economic feasibility.
