When I test a generator let's say 400kVA 0.8 pf 380V 3-phase on a unity power factor should I get a 400kW and 400kVA on the controller's screen? Because as we know in 1 pf KW= KVA but in 100% load I get 320kW 100% load and 320kVA 80% load. I can never get 100% KVA with 1 pf or the generator will fall down.
Why is that?
