Electrical Engineering MCQ on Transformer
If percentage impedances of the two transformers that are working in parallel are different, then
- Parallel operation will be not possible
- Parallel operation will still be possible, but the power factors at which the two transformers operate will be different from the power factor of the common load
- Power factors of both the transformers will be same
- Transformers will be overheated
Correct answer: 2. Parallel operation will still be possible, but the power factors at which the two transformers operate will be different from the power factor of the common load
