Test results of a three phase HTS transformer with double pancake windings

Abstract

This paper described construction and test results of a 10 kVA HTS transformer. Three phase transformer with double pancake windings were constructed. BSCCO-2223 wire, silicon sheet steel core and FRP cryostats were used in that transformer. After the test of basic properties of the 3 phase HTS transformer using no load test, short circuit test and full load test, continuous operation of 100 hours with pure resistive load has been carried out. Test results proved overload capability and reliability of the HTS transformer.
