Numerical analysis of the AC loss in a high-TC superconducting cable measured by calorimetric method

We calculated the AC property in a high-TC superconducting (HTS) cable fabricated by Furukawa Electric Industries Ltd (FEI) by using an electric-circuit (EC) model. The AC loss of the HTS cable is measured by a calorimetric method by FEI. The measured AC loss and the calculated one are almost equal. According to the calculated results, the layer's currents are uniform on the low transport current. On the high transport current, the layer's current distribution indicates a drift-current phenomenon.
