Electrical Engineering XYZ MCQs
Stray losses in transformer occurs in:
- Transformer insulating oil
- Paper insulation in transformers
- Steel core
- Winding conductors and steel structures of transformer
Correct answer: 4. Winding conductors and steel structures of transformer
Explanation: Stray losses occur in the winding conductors due to resistance and inductance effects. Additionally, stray losses also occur in the steel structures of the transformer due to eddy currents induced by the alternating magnetic fields. These losses are termed stray losses because they are not part of the intended energy transfer process but rather represent energy dissipated as heat due to non-idealities in the transformer’s design and operation.
