Q.

The synchronous impedance method of finding the voltage regulation of a cylindrical rotor alternator is generally considered as

  • AA pessimistic method because saturation is not considered
  • BAn optimistic method because saturation is not considered
  • CA fairly accurate method even if power factor is not taken into account while determining synchronous impedance
  • DA fairly accurate method when power factor is taken into account while determining synchronous impedance
Correct Answer : (A)

A pessimistic method because saturation is not considered

Hints :

The synchronous impedance method of finding the voltage regulation of a cylindrical rotor alternator is generally considered as A pessimistic method because saturation is not considered.
