Abstract

Due to the remarkable progress of AC superconducting wires, superconducting power transformers, which have the advantages of the reduction of size, weight and loss, are being investigated actively. However, considering the auxiliary facilities such as an outer cryogenic system, these advantages of the superconducting transformer over the conventional transformer are unclear. Thus, in this paper, a comparison of the size, weight and loss of superconducting transformers including auxiliary facilities with those of conventional transformers having the same output volt-ampere capacity is made. From the results of the comparison, the advantages of superconducting transformers are clarified.<>
