When two D.C. series generators are running in parallel, an equilizer bar is used________________?
Correct answer: C. so that two similar machines will pass approximately equal currents to the load
- A. to increase the speed and hence generated e.m.f.
- B. to increase the series flux
- C. so that two similar machines will pass approximately equal currents to the load
- D. to reduce the combined effect of ar-mature reaction of both machines
Explanation
In parallel series generators, the equalizer bar provides a common connection for the armature currents and keeps the series-field effects balanced. Consequently, similar machines share the load current approximately equally.
