Abstract :
THE CHARACTERISTICS of the interrupting device may have an appreciable effect on the recovery voltage obtained on interrupting an a-c circuit. This effect may appear as (a) an abrupt cutting off of the current, (b) the introduction of an arc voltage, or (c) the gradual introduction of a resistance. The recovery voltage may be either increased or decreased, depending upon how rapidly the resistance (or arc voltage) increases, and upon when it is introduced.
