Abstract

Second-generation (2G) HTS tape with stainless steel (SS) lamination is found suitable in limiting the fault current. The feasibility of tape to be used in SFCL has been characterized by AC conditions. DC measurement has been done to measure critical current (IJ and the quality index (n), which signifies the quality of the superconductor. The prospective fault currents at various voltages (20V , 40V , and 60V ) have been measured. Amodular SFCL unit has been developed using 75cm of HTS tape. The SFCL unit limits the fault current by about 7 times within 160 milliseconds and the corresponding recovery time recorded is 8.5 seconds. This paper briefly explains the test results of the AC characterization of SS- laminated HTS tape.
