Q.

The negative phase sequence in a 3-phase synchronous motor exists when the motor is 

  • AUnder loaded
  • BOverloaded
  • CSupplied with unbalanced voltage 
  • DHot
Correct Answer : (C)

Supplied with unbalanced voltage 

Hints :

The negative phase sequence in a 3-phase synchronous motor exists when the motor is Supplied with unbalanced voltage.
