A conceptual design of a high-Tc-based resistive-type superconducting fault current limiter (SFCL) using second-generation coated conductors (CCs) has been carried out in this paper for possible power applications in India. In the design aspect, noninductive SFCL coils made with stabilizer-free CCs have been used for analytical calculations. In electrothermal analysis, a short-circuit characterization has been simulated to get the maximum resistance and temperature achieved during fault limitation in a 440 V/800 A single-phase SFCL. Furthermore, the recovery under no load is studied, and recovery time is calculated.
