Q.

Zero sequence impedance of a 3-phase cage induction motor is due to

  • AStator circuit 3rd time harmonic
  • BStator circuit 3rd space harmonic
  • CRotor circuit 3rd time harmonic
  • DRotor circuit 3rd space harmonic
Correct Answer : (B)

Stator circuit 3rd space harmonic

Hints :

Zero sequence impedance of a 3-phase cage induction motor is due to Stator circuit 3rd space harmonic.
