ABSTRACT:
A polyphase sector type transformer includes one magnetic core ring per phase, each of which has two rectilinear sides which are adjacent to each other. Each rectilinear side of one magnetic core ring is disposed contiguously with one of the rectilinear sides of an adjacent core ring whereby each magnetic core ring occupies a sector of the magnetic circuit of the transformer. Each pair of contiguous rectilinear sides is threaded through a coil of the transformer said coils comprising a high tension winding of trapezoidal cross-section and a low tension winding of rectangular cross-section. Each magnetic core ring
