The a.c. the armature winding of an alternator operates at _______ the field winding.

  • The a.c. the armature winding of an alternator operates at much higher voltage than the field winding.
  • The AC armature winding of an alternator typically operates at a much higher voltage than the field winding.
  • The power rating and design of the alternator determine the voltage level of the armature winding.
  • For example, in a 1 MVA alternator, the AC armature winding may operate at several kilovolts, whereas the DC field winding may operate at several hundred volts.
  • This difference in voltage is due to the different functions of the two windings.
  • The AC armature winding is responsible for generating the output voltage of the alternator, which is typically a much higher voltage than the voltage required to excite the DC field winding.
  • The DC field winding generates the magnetic field that interacts with the AC armature winding to produce the output voltage.
  • Overall, the AC armature winding of an alternator operates at a much higher voltage than the field winding due to the different functions of the two windings.
