What do you mean by pf of a generator? Power factor purely
depends on the load (wether inductive, reactive or unity)
then what does the pf mentioned on the generator nameplate
means?

Answer Posted / balajieee
power factor is the cos angle between voltage¤t.using
that nameplate pf value u can find kw capacity of a
generator for its kva rating(formula,p=sqrt3*v*i*cospi.).if
you are connecting pure resistive load means power factor
is unity,so the pf of generator will incrase from its name
plate value.capacitive load also incrase the pf of
generator.inductive load will decrease pf value.so the
average of resistive,inductive,capacitiveload pf ,name
plate pf will give final output pf of generator.
