The T-A formulation has proved a fast and reliable method for the evaluation of AC losses in superconducting tapes, and has been successfully applied to complex geometries such as racetrack coils, CORC ® cables, and twisted stacked tapes conductors in either applied magnetic field or self-field. In particular the T-A formulation was used for the evaluation of AC losses in CORC ® cables made of striated superconducting tapes in an external applied field, with a null transport current. In this paper, the T-A formulation is adopted to evaluate the AC losses of stacked striated HTS tapes, representative of the straight section of a racetrack coil, with a sinusoidal transport current.
