DC Generators When two D.C. series generators are running in parallel, an equalizer bar is used To reduce the combined effect of armature reaction of both machines To increase the speed and hence generated e.m.f. So that two similar machines will pass approximately equal currents to the load To increase the series flux To reduce the combined effect of armature reaction of both machines To increase the speed and hence generated e.m.f. So that two similar machines will pass approximately equal currents to the load To increase the series flux ANSWER DOWNLOAD EXAMIANS APP
