Why alternators are rated in KVA?

Answer / ramprasad thorat
as the copper loss depends on current and core loss depend
on voltage so it is easily possible to find the efficiency
of the alternator. also at the time of manufactoring we dont
know the power factor of the load. so the alternators rating
is in VA.

Answer / nitin
as the load (i.e. resistive /inductive / capacitive )on the
alternator / transformer is not defind so that the
laternator / transformer rating in kva.
kw= sqrt3*v*i*cosQ
resistive p.f=0,
inductive p.f=lagging
apacitive p.f.=leading
