Electrical Engineering XYZ MCQs
Essential conditions for two DC generators are connecting for parallel operation is:
- Polarities should be same
- Rating of generators should be same
- Both of the above
- Terminal voltage should be same
Correct answer: 4. Terminal voltage should be same
Explanation: When generators are connected in parallel, their terminal voltages must match to ensure that the loads connected to the parallel system receive a consistent voltage level. If the terminal voltages of the generators are different, it can lead to unequal distribution of load and voltage fluctuations across the system, which can result in instability and potential damage to connected devices.
