Q.

If the frequency of input voltage of a transformer is increased keeping the magnitude of voltage unchanged, then

  • ABoth hysteresis loss and eddy current loss in the core will increase
  • BHysteresis loss will increase by eddy current loss will decrease
  • CHysteresis loss will decrease but eddy current loss will increase
  • DHysteresis loss will decrease but eddy current loss will remain unchanged
Correct Answer : (D)

Hysteresis loss will decrease but eddy current loss will remain unchanged

Hints :
Previous

If a sinusoidal voltage source is connected to a power transformer, it's no load current would be

Next

On no load phasor diagram of transformer, the core loss component of the current remains in phase with
