A professional center is supplied by a balanced three-phase source. The center has four plants, each a balanced three-phase load as follows: Load 1: 150 kVA at 0.8 pf leading Load 2: 100 kW at unity pf Load 3: 200 kVA at 0.6 pf lagging Load 4: 80 kW and 95 kVAR (inductive) If the line impedance is 0.02 + j0.05 N per phase and the line voltage at the loads is 480 V, find the magnitude of the line voltage at the source.
