Abstract :
A. N. Garin (General Electric Company, Pittsfield, Mass.): This paper is, in my opinion, a welcome and perhaps even an overdue addition to the still rapidly growing literature of the method of symmetrical components. Although the fundamental principles and even the formulas for expressing the current and voltage vectors of a four-phase system in terms of their symmetrical components, and vice versa, have been published quite some time ago, as indicated by the references given in the paper, this, so far as I know, is the first presentation of the formulas for the fault currents.
