Abstract

The superconducting windings of the air-core superconducting power transformer have possibilities of being exposed to a higher magnetic field than those of the iron-core transformer because of no special paths for magnetic flux. Thus, in this paper, the magnetic field and electromagnetic force acting on the windings of an experimental 3-phase air-core superconducting transformer are analyzed. From the results, it has become clear that the superconducting windings of the air-core transformer are exposed to a 3-dimensional magnetic field containing a rotational component
