A Resistive-Type Modular Superconducting Fault Current Limiter Fabricated With Stainless-Steel-Stabilized YBCO Tapes

A resistive-type superconductor fault current limiter (SFCL) is experimentally studied with stainless-steel-stabilized 12-mm-wide YBCO tapes. The SFCL is assembled with six noninductive modules, each rated for 120 V, 100 A. The module has several YBCO tapes connected in series that are arranged such that the flow of current in one tape is in the opposite direction from its neighboring tapes. The modules can be connected for different SFCL configurations with series and parallel combinations. In this paper, the SFCL is assembled in two configurations and is tested for continuous, overload, and short-circuit currents. The first configuration is assembled to evaluate current carrying performance in parallel connected modules at 600 A. The second configuration is assembled for short-circuit performance of two series-three parallel connected modules at 240 V, 300 A. The evaluated data will be useful to develop higher rating SFCL with modular construction.
