The ‘synchronous impedance method’ of finding the voltage regulation of a cylindrical rotor alternator is generally considered as
A. a pessimistic method because saturation is not considered.
B. an optimistic method because saturation is not considered.
C. a fairly accurate method even if power factor is not taken into account while determining synchronous impedance.
D. a fairly accurate method when power factor is taken into account while determining synchronous impedance. [U.P.S.C. I.E.S. 2002]
