In this paper simulation of the alternating current loss (AC loss) in a high temperature superconducting tape and a HTS cable having 4 layers of polygon conductors using COMSOL Multiphysics software has been reported. The simulation results for the single rectangular tape are verified with the Norris equation for a HTS tape. The effect of increased number of layers on AC loss is also observed using the simulation. All the simulations are done using two dimensional cross-section of HTS tape and the multiple numbers of tapes are assembled to form the polygon conductor. Using A-V formulation, the dynamic electromagnetic analysis has been done. For this, two dimensional PDE based module of COMSOL Multiphysics has been used with two dimensional geometry with proper Dirichlet and Neumann boundary conditions.
