Three parallel loads are supplied by a voltage source with a voltage of 4160 angle (0) (rms). Load 1 is 240 kVA at a power factor of 0.8 lagging and load 2 is 160 kVA at a power factor of 0.92 lagging. The third load requires 120 kW.
(a) Draw the power triangles for load 1 and load 2; label all sides and the power factor angle with appropiate numerical values.
(b) Calculate the impedance and current phasor for load 1
(c) Calculate the impedance and current phasor for load 2
(d) Design the power requirements for load 3 so that the source voltage and the current drawn from the source are in phase. Draw the power triangle for load 3 and label all sides and the power factor angle with appropiate numerical values.
(e) Find the power factor for load 3
(f) What is the magnitude of the current drawn from the source to supply the three parallel loads?
