Abstract

YBCO coated conductor (CC) wires has many advantages for resistive superconducting fault current limiters (SFCLs). Especially, the 344S manufactured by AMSC CC clad with stainless steel can reduce fault current to lower temperature because stainless steel stabilizer roles as higher resistant shunt. Multi parallel structure is inevitable for SFCLs with large current capacity. The two layered with four parallel paths non-inductive wound solenoid coils were fabricated. The inductances of inner and outer layers were calculated using finite element method (FEM) tool. These results were compared with measured values. In this paper, the current distribution characteristics of coils were measured when 240 Apeak was applied. From the experiments, the results show that more large current flows into inner layers by difference in inductance. Therefore, the two solenoid coils was transposed to reduce of non-uniform current distribution between inner and outer layers by electrical inductance. The experimental results provide to suitable design parameters and showed technical feasibility of multi parallel structure.
