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