Asymmetrical loading of three-phase three-winding transformer banks

W. C. Sealey (Allis-Chalmers Manufacturing Company, Milwaukee, Wis.): This paper is interesting, because it demonstrates the similarity of problems and their solutions by engineers, regardless of geographical location. Asymmetrical loading of three-phase three-winding transformer banks in which a single-phase load is superimposed on a three-phase load does not present too common a problem in the United States. However, the author solves this problem in exactly the same manner using exactly the same equations as similar problems have been solved in this country. The equations used are familiar.
