A three-phase abc -sequence wye-connected source with V an = 220 0° V rms supplies power to a wye-connected load that consumes 50 kW of power in each phase at a pf of 0.8 lagging. Three capacitors are found that each have an impedance of j 2.0 ,, and they are connected in parallel with the load in a wye configuration. Determine the power factor of the combined load as seen by the source.
