Abstract

To demonstrate the applicability of super-conductors to electric power machines, the authors made and tested a small single-phase superconducting transformer. The aim of the study was to determine the fundamental properties of superconducting trans former. Therefore the superconducting transformer has a simple structure, i.e. the high voltage to low one ratio is 2:1 and the iron core is immersed in liquid helium. Fundamental characteristics are obtained through no-load and short-circuit tests. In this paper, the experimental results are described.
