A second-generation high-temperature superconductor (HTS) based superconducting fault current limiter (SFCL) module has been characterized by different prospective fault currents at the output voltages of 20 Vrms and 40 Vrms. The current limiting characteristics of the modular SFCL unit and their recovery under load characteristics have been analyzed. The dynamic thermal profiles of the HTS tape during the fault and recovery have been studied experimentally at liquid nitrogen temperature. This paper briefly presents the investigation of the behavior of YBCO tape-based modular SFCL unit at the 20 Vrms and 40 Vrms.
