Abstract: Based on the finite element method (FEM), a simulation model of a single-phase HTS transformer was established according to a developed HTS transformer, and the simulation results are in good agreement with the experimental data. On this basis, a 120kVA/6kV single-phase HTS transformer was designed, the primary windings were solenoid coils consisted of 8 helically wound layers, and the secondary windings were consisted of 13 double pancakes connected in parallel with 9 layers. The current distribution in windings, magnetic field and stress analysis under rated working condition and in fault were simulated. The results are important to the design of HTS transformer.
