Q1. Two loads Z, 10 + j20 N , Z2 100 – j270, N are connected across a Vs=400Vrms, 50 Hz, source as shown in fig. 1. a) Find the total real power, the reactive power and the power factor at the source, and the total current in uncompensated case (i.e. when no compensation capacitor C is connected to the loads). b) Find the capacitance of the shunt compensation capacitor C to be connected across the loads to improve the overall power factor to 0.866 lagging. 12 R1 10 Ohm R2 Vs 100 Ohm C2 - j270 Ohm L1 +j20 Ohm fig.1
