Short-circuit test on an induction motor cannot be used to determine___________?
Correct answer: A. windage losses
- A. windage losses
- B. copper losses
- C. transformation ratio
- D. power scale of circle diagram
Explanation
In the blocked-rotor test the motor is stationary, so windage loss is zero and cannot be measured from this test. Copper losses, transformation ratio, and circle-diagram power scale can be obtained or determined using the test data.
