(5.32) A small plant has a bank of induction motors that consume 64kW at a PF of 0.68 lagging. The 60Hz line voltage across the motors is 220 ∠ ∘ V rms. The local power company has told the plant to raise the PF to 0.92 lagging. What value of capacitance is requited? Last updated: 10/31/2006 4:03:55 PM 2/3 12.
