  • The power burden of high-$T_c$ superconducting (HTSC) elements comprising superconducting fault current limiter (SFCL) using magnetic coupling of shunt reactors was analyzed. The magnetically coupled shunt reactors play a role in distributing the even power burden between HTSC elements comprising the SFCL, which contributes to the effective current limiting and recovery characteristics of the SFCL. It was confirmed through the comparative analysis on the SFCLs with both the magnetically coupled and the magnetically uncoupled shunt reactors that the magnetically coupled shunt reactors could improve the SFCL's performance by equalizing the power burden of HTSC elements.

  • The current limiting and recovery characteristics of a superconducting fault current limiter (SFCL) using shunt reactors were analyzed. Generally, the shunt reactor has a role to distribute the even voltage drop between high-Tc superconducting (HTSC) elements comprising the SFCL. However, the shunt reactors magnetically separated was not contributed to the equal voltage distribution between the HTSC elements. Through the experiments for the SFCL with both the magnetically coupled and magnetically uncoupled shunt reactors, the magnetically coupled shunt reactors were confirmed to improve the current limiting and recovery characteristics of the SFCL.
