Performance of auto transformers with tertiaries under short-circuit conditions

L. F. Blume: The subject of the paper by Messrs. Mini, Moore and Wilkins involves many interesting problems because the transformer connection to which the authors mostly refer is a mongrel which has inherited its pecularities from three distinct sources. For, in this one transformer connection are combined the various aspects of (a) an auto transformer, (b), the Y connection, and (c) the 3-winding transformer. I will pointout briefly for purposes of emphasis, a few of the salient characteristics of only one of them, namely, the 3-winding transformer.
