Abstract: A split winding assembly for a transformer is configured to extend along a main limb of a transformer core between a first end and a second end. The split winding assembly includes a first split winding section extending from the first end toward a midpoint of the split winding assembly and a second split winding section extending from the second end toward the midpoint of the split winding assembly along the main limb of a transformer core. The first split winding section includes a first inner winding section configured to surround the main limb of the transformer core and a first outer winding section surrounding the first inner winding section. The second split winding section includes a second inner winding section configured to surround the main limb of the transformer core and a second outer winding section surrounding the second inner winding section.
