Abstract :
C. A. Woods, Jr. (Westinghouse Electric and Manufacturing Company, East Pittsburgh, Pa.): This paper, like the Gebelein-Elzi (Transactions pages 541–6) and Woods — Bottonari (Transactions pages 554–60) papers, proposes a method of calculating the steady-state performance of current transformers from their fundamental data; consisting of the excitation characteristics, and the values of secondary resistance and leakage reactance. It differs from these other papers in that it is not restricted to bushing-type current transformers, in which the leakage reactance has usually been found sufficiently small that it may be neglected for most relay applications.
