A 3-phase 4160 V Y-connected source is rated at 5 MVA. It is connected to a balanced 3-phase delta connected load with 300 A phase current at 0.8 p. f. Determine the impedance of the load, and the source line current and power factor seen by the source. What impedance can be added to the system to make the power factor = 1?
