Effect of magnetic fields due to electric currents in an HTS power cable and estimation of stress de Souza Isaac1,*, Anand Ankit1, Gour Abhay Singh1, Rao Vutukuru Vasudeva1 1Cryogenic Engineering Centre, Indian Institute of Technology, Kharagpur *E-mail ID: isaacdesouza68@gmail.com
Online published on 4 December, 2023. Second generation High Temperature Superconducting (HTS) tapes are generally wound around a former in a helical manner for HTS power cables. The high current flowing through the individual tapes results in a magnetic field around each tape. The effect of the magnetic field is attraction between the tapes resulting in forces induced by each tape on its neighbors. The stresses induced may result in reduction of the critical current of the tapes thus degrading performance of the HTS power cable. The objective of this study is to numerically analyze the effect of magnetic fields as a result of electric current flowing in the cable and estimate the stresses in the cables. A parametric study with different pitch winding angles and different electric currents has been carried out to determine the stresses induced inside the HTS tapes.
