The power √3 VL IL Cos
φ delivered by the alternator for the same value of current, depends
upon p.f. (Power Factor=Cos φ) of the load. But the alternator
conductors are calculated for a definite current and the insulation at
magnetic system are designed for a definite voltage independent of p.f.
(Cos φ) of the load. For this reason apparent power measured in kVA is
regarded as the rated power of the alternator.
Why alternator rated in kVA. Not in kW?
