Abstract
A 40 k VA three phase superconducting transformer has been developed a nd tested. From the test results, excellent voltage regulation of 0.3% with a pure resistive load was obtained. As a usage in a power system , parallel operation with a conventional transformer using copper wind ings has been carried out, Although a superconducting transformer cann ot continue to operate in case of quenching, the proposed parallel sys tem can overcome came the drawback and give us an additional value of fault current limiting function.
