Hopkinson's test on D.C. machines is conducted at_______________?
Correct answer: C. full-load
- A. no-load
- B. part load
- C. full-load
- D. overload
Explanation
Hopkinson’s test is a regenerative back-to-back test in which one machine operates as a motor and the other as a generator, normally at full load. It therefore measures performance under practical full-load conditions with relatively low power input.
