P12.7-7 (Dorf and Svoboda, 7 th ed) slightly modified: A manufacturing plant can be represented as two loads connected in parallel each requiring a line voltage of 4.16 kVrms. Load 1 is 1.5 MVA, 0.75 lagging, delta-connected. Load 2 is 2 MW, 0.8 lagging, Y-connected. The feeder from the power utilitys substation transformer has an impedance of (0.4 + j0.8) /phase. Determine the following: a) The required magnitude of the line voltage at the substation. b) The real power drawn from the supply. c) The percentage of real power drawn from the supply that is consumed by the loads....
