APPLICATION OF ERIK PERSSON AND JOHNNY SUNDIN FLUX CONTROL IN TAPE WINDINGS ABSTRACT OF THE DISCLOSURE Disclosed are improved constructions for power transformers and reactors having windings of tape-formed conductor material which tend to reduce additional losses in the windings. In the improved construction for a power transformer or reactor comprising a core containing magnetic material and having legs and a yoke and comprising windings including a tape-formed conductor material arranged concentrically around the core legs, the innermost of the windings has a first portion located nearest the core leg which has an axial length greater than the length of the portion of the winding located radially outside said first portion. The first portion thereby forms a cylindrical shield for controlling the magnetic leakage flux appearing outside the ends of the winding.
