Unformatted text preview: delivered or the source voltage, what must the component value of the load be? 3 . A voltage source serves the following loads, which are all connected in parallel: Load 1 – 18kVA at PF=.8 lagging Load 2 – 10kVA at PF=.7 leading Load 3 – 12kW at PF = 1 Load 4 – 16kVA at PF=.6 lagging The magnitude of the source voltage is 208 volts rms. a) Find the phasor impedance of each load and the phasor current of each load. b) Find the magnitude of the source current. c) Find the power factor of the combined loads as seen by the source. d) Find the total complex power delivered by the source. e) Design a corrective load that will decrease the source current magnitude by 20%. Is such a load possible?...
