A factory has an electrical load of 1600 kW at a lagging power factor of 0.8. An additional variable power factor load is to be added to the factory. The new load will add 320 kW to the factory. The power factor of the variable power factor load is to be adjusted so that the overall power factor of the factory is 0.96 lagging. a) What is the reactive power associated with the added load? b) Does that load absorb or deliver magnetising vars (reactive power is also sometime referred to as magnetising vars. Inductors absorb magnetising vars and capacitors deliver magnetising vars) c) What is the power factor of the adjustable power factor load? d) If the voltage at the input is 2400 V (rms), what is the magnitude of the current into the factory before the adjustable load? e) What is the magnitude of the current with the adjustable load?
