DC Generators If a self excited D.C. generator after being installed, fails to build up on its first trial run, the first thing to do is to check armature insulation resistance increase the field resistance increase the speed of primemover reverse the field connections check armature insulation resistance increase the field resistance increase the speed of primemover reverse the field connections ANSWER DOWNLOAD EXAMIANS APP
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. So that the two identical machines will pass approximately equal currents to the load To reduce the combined effect of armature reaction of both the machines To increase the series flux To increase the generated e.m.f. So that the two identical machines will pass approximately equal currents to the load To reduce the combined effect of armature reaction of both the machines ANSWER DOWNLOAD EXAMIANS APP
