what is the effect of PF on alternator sizing?

Answer Posted / kalidassallinterview

Generaly the generator is run in lagging power factor only.
If we tryed to increase the power factor to unity, then the
generator will be overloaded.Ex: 750KVA,0.8PF generator we
can connect up to 600KW load. If we increase the power
factor to unity there is a chace to connect extra true
power up to 750KW. so the engine will be load.
