Oscillographic Study of Alternator Short Circuits

The purpose of this investigation was to study the effect of introducing inductance into the field circuit for the purpose of reducing the initial transient peak during a short-circuit of an alternator, and to verify certain theoretical equations with actual experimental figures. This experiment is a continuation of the studies begun by students at Cornell University. The work described in this paper was done under somewhat different conditions from the work at Cornell; namely, a salient pole machine was used in place of a non-salient pole machine.
