I'm not sure what you are looking for, but the J&P Transformer Book by M.Heathcote is a good reference.
ISBN: 0750611588
I think it is the 12th edition of this "bible" of power transformers.
of Trf engineering is the old GE book written by L F Blume ,Boyajin etc covering fundamentals .Book by Karsai gives the design details and calculation formulae.J&P covers application,operation maintenance aspects more from a user angle.More recent books covers the calculations under the computer environment.
