SUMMARY
The discussion focuses on calculating the power factor for a balanced 3-phase AC system with a load of 100kW at a voltage of 12500V. The initial power factor is 0.75, and the goal is to improve it to 0.90 lagging by determining the required capacitor size. The calculations reveal that a capacitor of 0.416mF is necessary, and the real power remains constant at 520kW. The reactive power before and after the capacitor installation is calculated as 321kVAR and 151.62kVAR, respectively.
