Abstract :
In this paper, the analytic algorithm using equivalent magnetization curves is proposed for analysis of the three-phase transformer with wound-core in consideration of a step-lap joint or noncut structure. Influences of differences in step-lap joints and noncut structures on equivalent magnetization curves are examined using the algorithm. Influences on the exciting currents and core losses of the three-phase transformer are also examined
