Which of the following properties is not necessarily desirable for the material for transformer core ?
Correct answer: C. High thermal conductivity
- A. Low hysteresis loss
- B. High permeability
- C. High thermal conductivity
- D. Adequate mechanical strength
Explanation
Low hysteresis loss, high permeability, and adequate mechanical strength are important core-material properties. High thermal conductivity is not essential because transformer cores are designed primarily for magnetic performance and low loss.
