DC Generators When two D.C. series generators are running in parallel, an equalizer bar is used 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 To increase the speed and hence generated e.m.f.

DC Generators In D.C. generators the polarity of the interpoles Is opposite to that of the main pole ahead Is the same as that of the immediately preceding pole Is neutral as these poles do not play part in generating e.m.f. Is the same as that of the main pole ahead Is opposite to that of the main pole ahead Is the same as that of the immediately preceding pole Is neutral as these poles do not play part in generating e.m.f. Is the same as that of the main pole ahead ANSWER DOWNLOAD EXAMIANS APP
