Abstract

The paper presents a valuable extension to the new method of estimating total AC loss in solenoidal high temperature superconducting windings of the transformer type, where losses caused by external magnetic field and due to transport current are modeled together. This complex problem is solved using a highly nonlinear 2D finite difference formulation in the superconductor in combination with a linear finite element model representing the rest of the transformer. Comparison with measurements on a real device shows good agreement and validates the method as a practical tool
