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.
