Abstract
In sheet-wound transformer coils, excessive ohmic losses due to high current density at the sheet edges caused by a radial magnetic leakage field are avoided by adding apparatus adjacent the edges which may comprise individual strips that are transposed as the coil is wound. In one alternative embodiment, the apparatus adjacent the edges comprises separate parallel strips of high magnetic permeability material assembled in conjunction with the coils. In another alternative embodiment, wire-wound coils are employed at each edge of the sheet-wound coils.
