SUMMARY
This discussion focuses on power factor correction for two loads connected in parallel, with specific parameters: Vs = 480<0 rms, P1 = 105 W (pf1 = 0.7 lagging), and P2 = 5 × 104 W (pf2 = 0.95 leading). The key conclusion is that to correct the power factor, one must first calculate the reactive currents of both loads to determine if the overall system is capacitive or inductive. If one load has a leading power factor, it does not require additional capacitance, while the lagging load may require it. The total capacitance can be calculated by adding the individual capacitances of both loads if necessary.
