Hysteresis loss in a transformer varies as CBmax = maximum flux density) ?
Correct answer: B. Bmax1-6
- A. Bmax
- B. Bmax1-6
- C. Bmax1-83
- D. B max
Explanation
By the Steinmetz relation, hysteresis loss is approximately proportional to Bmax^1.6, where Bmax is the maximum flux density. Thus the option showing the exponent 1.6 is intended.
