Abstract :
A single-phase power transformer with windings made of T/sub c/ superconducting tapes was fabricated and tested. The tapes are made of Bi-2223 imbedded in a silver alloy matrix. The primary and secondary windings are made of double pancake coil. The rated voltages of the windings are 220/110 V. Four pancake type coil windings are stacked on the core. The inner two act as the primary winding. Fundamental characteristics are obtained through short circuit and no load tests. The overload capability and characteristics are investigated.
