A Y-connected capacitor bank is connected in parallel with the loads of Problem 2.13. Find
a) The total kvar and capacitance per phase in uF to improve the overall power factor to 0.8 lagging.
b) The corresponding line current.
Problem 2.13
Three loads are connected in parallel across a 12.47 kV three-phase supply. The first is a resistive 60 kW load, the second is a motor (inductive) load of 60 kW and 660 kvar, and the third is a capacitive load drawing 240 kW at 0.8 p.f. Find the total apparent power, power factor, and supply current.
