Superconducting cables have shown the advantages in large power transmission with higher efficiency and lower loss. In particular, the application to DC electric system is now attracting increasing attention. However, after introduction of superconducting cables, the increased fault current may be a threat to the safety and stability. To cope with this issue, the resistive SFCL offers one of the most ideal solutions due to its operating principle and limiting performance. This paper discusses the influence of three main design parameters of resistive type SFCL with a model DC system using superconducting cables, and proposes the design method and criterion. Then, the electromagnetic and thermal design of the SFCL is discussed for two model systems: low voltage HTS DC distribution system and high voltage HTS DC transmission system. Furthermore, it is shown that how the differences in system characteristics influence the design of SFCL.
