Question 483Electricity & Electronics - Assistant Engineer

The correct answer is D) The series fields of both generators are connected in parallel. In a compound wound DC generator, the series field winding is responsible for maintaining equal load sharing between generators operating in parallel. By connecting the series fields of the two generators in parallel, any change in the load current of one generator will be reflected in the other, ensuring that the load is equally distributed between the two generators. The other options are incorrect because: A) Interconnecting the shunt field rheostats will not affect the load sharing between the generators. B) Interconnecting the shunt fields alone will not ensure equal load sharing. C) Connecting the series fields in series would not allow for the required load sharing mechanism.
