The DC excitation to the field of brushless synchronous is generally produced by ()
The most common source of excitation for synchronous motors is a/an ().
Generators should have an excitation/voltage regulation system which will enable them to share the steady state reactive load () no machine exceeds its proportional share of reactive load by more than 10% of the rated reactive load of the largest generator.
