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

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. 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 To reduce the combined effect of armature reaction of both machines ANSWER DOWNLOAD EXAMIANS APP
