Q. A single-phase industrial plant consists of two loads in parallel:
P1 = 48kW PF1 = 0.60 lagging
P2 = 24kW PF2 = 0.96 leading
It is operated from a 500-V, 60-Hz source. An additional capacitor C is added in parallel to improve the plant's overall power factor to unity.
Determine the value of C in µF. Also sketch the power triangles before and after the addition of C, and find the overall current drawn from the supply.
