Abstract :
This paper presents the performance evaluation of an HTS transformer. The design of the transformer was based on the BSCCO-2223 HTS tapes and double pancake windings. A total of four double pancake windings were used. Two of the windings were connected in series for the high voltage winding and two windings were connected in parallel for the low voltage winding. The characteristics of several winding arrangements were examined. The performance of the transformer during transient, which is caused by a sudden short circuit, was simulated. The current limiting effect, temperature rise and resistance growth of the superconducting winding were also shown.
