Two loads are connected in parallel across a line to line voltage 13 kV three-phase supply (Y-connected). Load 1: Inductive load, 60 kW and 660 KVAR. Load 2: Capacitive load, 240 kW at 0.8 power factor. a) If a Y-connected capacitor bank is connected in parallel with the loads. Find the the capacitance per-phase in µF to improve the overall power factor to 0.8 lagging. b) Compare the line current before and after power factor correction

Question
Two loads are connected in parallel across a line to line voltage 13 kV
three-phase supply (Y-connected).
Load 1: Inductive load, 60 kW and 660 KVAR.
Load 2: Capacitive load, 240 kW at 0.8 power factor.
a) If a Y-connected capacitor bank is connected in parallel with the
loads. Find the the capacitance per-phase in uF to improve the overall
power factor to 0.8 lagging.
b) Compare the line current before and after power factor correction
