Question

Problem 3 The Y-Y system in Figure below has a balanced load and a line impedance Zline = 3 Ω + j 15 Ω. If the line voltage at the generator is 12 kV and the total power delivered to the load is 900 kW at 60 A, determine each of the following: a) The magnitude of each phase voltage of the generator. b) The magnitude of the line currents. c) The total power delivered by the source d) The power factor of the entire load “seen” by the source. e) The magnitude and angle of the current IAa if Van = Van ∠ 0°. f) The magnitude and angle of the phase voltage VAN if EAN = EAN ∠ 0°. g) The impedance of the load of each phase in rectangular coordinates.
