Abstract :
H. A. Peterson and T. W. Schroeder (General Electric Company, Schenectady, N. Y.): The author presents a sound basis for evaluating the recovery-voltage transients for circuit interrupters in circuits having up to two natural frequencies of oscillation. The method employed rests on the firm foundation afforded by an intimate understanding of the principle of superposition. Its chief limitation from the standpoint of general usefulness lies in the fact that the arcing characteristics of a given interrupter must be known before it can be applied. Thus, a certain number of actual test or empirical data is prerequisite.
