Abstract

Worldwide development of superconducting power equipments by exploiting the 2G wire is continuously ongoing; moreover, superconductor wire manufacturing companies are also making constant efforts to develop superconducting power equipments for the purpose of increasing critical current density as well as improving homogeneity of the wire. Particularly, the development of resistive superconducting fault current limiter (SFCL) is making an active progress and related tests of superconducting wire are performed as well. For resistive SFCL, the superconducting wire with stainless steel stabilizer is more appropriate than that with copper since stainless steel generates more resistances per unit length than copper. Especially, AMSC in USA succeeded in developing coated conductor (CC) clad with stainless steel stabilizer. The stabilizer of 25 μm is laminated on the superconductor layer and under the substrate, both of which are electrically jointed with solder. By using the wire, the design and manufacture of resistive SFCL was performed. For the commercialization of resistive SFCL, it is one of the most key factors to decrease inductive reactance in the process of designing coils. Therefore, coils were wound by non-inductive winding method and their losses in normal condition were measured. Also, current limiting characteristics of the SFCL module wound with CC clad with stainless steel stabilizer were studied by short-circuit test.
