The Principles of the Transformer

Abstract

IN a work coming to us from one of the principal technical colleges in the United States, and on a subject which has been occupying the attention of electrical engineers for at least fourteen years, one would naturally expect to find a well-considered treatment based on the concentrated essence of practical experience, and embodied in a form which should definitely guide design and construction. It was therefore with a feeling of disappointment that we found so large a portion of this volume devoted to a class of investigations which are nothing more than elaborate mathematical exercises in the geometry of periodic quantities.
