A reverse approach to designing as-built transformers is presented in this paper. The physical characteristics and dimensions of the windings and core are the specifications. By manipulating the amount and type of material actually to be used in the construction of the transformer, its performance can be determined. Such an approach is essentially the opposite of the conventional transformer design method. The method is applied to two sample high voltage transformers. The measured performance of the transformers verifies the usefulness of using this reverse design approach.
