I-V characterization of HTS tape under tensile stress using cryogenic UTM along with FEM analysis

An indigenous Cryogenic Universal Testing Machine (C-UTM) capable of creating tensile strain in 2G HTS tape under superconducting state is developed. Stress-strain property of superpower make SCS4100 HTS 2G tape is measured using this and were used for FEM analysis. A suitable instrumentation was done to measure I-Vcharacteristic (4-Probe method) of HTS 2G tape under tensile strain using developed cryogenic UTM. I-V characteristics of 2G HTS tapes is used for developing HTS 2G tape based devices such as cables, motors, generators, Superconducting Fault Current Limiters(SFCL) and Superconducting Magnet Energy Storage(SMES).
