Abstract

In this paper, 3-D electromagnetic analysis of a single phase 1MVA 22.9kV/6.6kV High Temperature Superconducting(HTS) transformer with double pancake windings by using the OPERA 3D was accomplished. And in order to perform the analysis of leakage impedances of a 1MVA HTS transformer, the energy conservation method was used. The efficiency voltage regulation and ％ impedance voltage drop of a 1MVA HTS transformer were obtained by the analysis of leakage impedances.
