This problem has been bugging me as i used to be able to do this!
Ok we have 20KW @ 0.8Pf 200V/400Hz 3 phase power units for supplying power to aircraft. These are the manufacturers quoted figures.
We have a Resistive element load bank (no inductive elements)
The manufactures quote 72Amp maximum line currents per phase for this system.
Is this the true current (KW) or apparrent current (KVA) they have quoted?
As a learning curve for me, could someone show me the method of simply calculating the Kw, KVA and KVAR line currents that make up the 3, 4, 5 traingle (0.8PF) for this example of a 20 KW generator @ 0.8PF.
Any help apprehciated Regards Martin
