چکیده انگلیسی
The fastest effective fault limitation is one of the selection criterion of high Tc superconductors (HTS) for resistive type fault current limiter (R-SFCLs) application. In the present work, we have given a comparative DC & AC performance study on HTS tapes with and without stabilizer. At first, we have investigated the temperature dependent DC resistivity of the SS stabilized Bi2223 based conductor, Cu (50â¯Âµm substrate) and SS (75â¯Âµm substrate) stabilized YBCO based coated conductors (CCs) and compared with the stabilizer free YBCO based CC (50â¯Âµm and 100â¯Âµm substrate). We have studied the DC transport properties (E-I) of the stabilized and stabilizer-free tapes to obtain flux-flow resistance before reaching normal state, critical current and 'n' factor at 1â¯ÂµV/cm criterion. Further, the 1st peak limitation, response time and resistance attained during fault limitation have been compared for AC over-current pulses of 1.5 kA for 100â¯ms duration. The aforesaid measurements helped us to select a suitable high Tc superconductor for fastest effective fault limitation to be used in R-SFCL application.
