In a power transformer, if in place of sinusoidal wave, a peaked wave voltage is fed to the primary

  • ACopper losses will be less
  • BNoise level will be reduced
  • CIron losses will be more
  • DIron losses will be less
Correct Answer : (D)

Iron losses will be less

Hints :

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


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