Power transformers are generally designed to have maximum efficiency around__________?
Correct answer: C. near full-load
- A. no-load
- B. half-load
- C. near full-load
- D. 10% overload
Explanation
Power transformers operate near full load for much of their service, so they are designed for maximum efficiency near full-load conditions. Distribution transformers, in contrast, are often designed for maximum efficiency around half-load.
