D)windage losses

Question

Quizplus · Accepted Answer

The retardation test on D.C. shunt machines is primarily used to determine stray losses, which are not directly measurable by conventional methods. This test helps in calculating the total losses by subtracting the known losses (like copper losses, core losses, etc.) from the total losses, leaving the stray losses as the remainder.
