Abstract
A method and an apparatus for calculating the number of turns per segment of a transformer coil winding which has a plurality of segments connected in series. The number of turns per segments is computed by assigning to segments predefined parameters related to customer requirements. Then a system of linear equations is automatically generated and the equations are simultaneously solved.
