Performance of traveling waves in coils and windings

Abstract

THE reaction of coils and windings to traveling waves which impinge upon their terminals is an ever-important problem in electric power systems from both the practical and the scientific point of view. Transformers as well as alternators are used at increasingly higher voltages and their insulation is thus subjected to switching and lightning surges of ever-increasing severity. A simplified but nevertheless rigorous conception of the wave propagation within such windings may therefore be advantageous. It may be used for coils in communication circuits as well.
