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