This paper describes the construction and test results of a 10 kVA single phase HTS transformer. Double pancake windings with BSCCO-2223 HTS tape and GFRP cryostat with room temperature bore are used in the transformer. Two double pancake windings are connected in series to provide 94×2 turns and two double pancake windings are connected in parallel to conduct the secondary current of 45.4 A. Coefficients of the constructed transformer are obtained using fundamental tests of the transformer. According to the test results, a slightly larger leakage reactance than expected is observed due to the bulky core which surrounded the cryostat
