Of the several phenomena which occur in the armature ofan alternating current generator when it is subjected toshort-circuit, the one of most interest and importance isthe magnitude and duration of the first rush of the instant the short-circuit occurs the current is limitedonly by the self inductance of the armature, which varies inmagnitude as tne position of tne armature changes with respectto the field poles. it is evident, therefore, that the firstrush of current will vary in magnitude dinfluenceofvaryi00leee
