Abstract

The integrated three-phase superconducting fault current limiter (SFCL) using two superconducting circuits was conceptually designed and analyzed. The integrated three-phase SFCL system is an upgrade version of inductive single-phase SFCL systems. It uses one magnetic core having three legs, like a three phase transformer. Each leg has a copper winding as a primary winding but, as a secondary winding, only two legs have superconducting tubes and the other leg has no secondary winding. It has the same characteristics with inductive single-phase SFCL. Moreover it has other merits in stability, expense, and mechanical stress.
