Electrical Engineering MCQ on Transformer
Two transformers are connected in parallel configuration. These transformers do not have equal percentage impedance. Such a situation will likely cause
- Loading of the transformers not in proportion to their kVA ratings
- Power factor of one of the transformers is leading while that of the other lagging
- Short-circuiting of the secondaries
- Transformers having higher copper losses will have negligible core losses
Correct answer: 1. Loading of the transformers not in proportion to their kVA ratings
