Which of the following property is not necessarily desirable in the material for transformer core ?
Correct answer: C. High thermal conductivity
- A. Mechanical strength
- B. Low hysteresis loss
- C. High thermal conductivity
- D. High permeability
Explanation
Transformer-core material should have high permeability, low hysteresis loss, and adequate mechanical strength. High thermal conductivity is not an essential requirement for the magnetic core material, so it is the property not necessarily needed.
