Abstract :
The feasibility of a UHV superconducting transformer(SCT) in an electric power system is studied. A 1100/550kV, 1750MVA SCT is conceptually designed, which has windings of ultra-fine filament superconducting wire and an amorphous alloy core. The total loss of the SCT is calculated to be about 300kW at room temperature assuming that the refrigerator efficiency is 1/500. In this calculation, the heat leak loss, stray loss, etc. are included. This value of the total loss is about 20 - 25% of that of conventional transformers.
