Reducing the amount of effective materials is a problem that needs to be solved urgently in the manufacture of transformer. The optimum design is the main way to solve this problem. In this article the optimum dimension of iron core is discussed under the condition that the rated capacity, voltage regulation coefficient, md'tiction of iron core, and the Other relative coefficients and parameters are supposed to be given, so that the goal for saving effective materials and lowering the cost can be achieved. Moreover, an example is given to illustrate this method, and the result is desirable. The algorithm of this article is suitable for the transformer with smaller short circuit ratio and lower voltage, which has wider range of usage whether as power transformer or as special one.
