Electrical Engineering XYZ MCQs
What is the advantage of parallel operation of alternators:
- Increase efficiency under light load conditions
- Continuity supply is maintained
- Increase in reliability
- All of the above
Correct answer: 4. All of the above
Explanation:
- Increase efficiency under light load conditions: Parallel operation allows alternators to share the load efficiently, avoiding overloading of a single unit and enabling them to operate closer to their optimal efficiency level.
- Continuity of supply is maintained: If one alternator fails, others can continue supplying power, thus ensuring an uninterrupted power supply.
- Increase in reliability: By distributing the power load among multiple alternators, the system’s overall reliability increases as the failure of a single alternator does not lead to a total system failure.
Therefore, all these factors contribute to the advantages of parallel operation of alternators.
