QUESTION 3 Based on the circuit shown in Figure Q1, the star-connected three-phase supply is connected to balanced delta-connected loads. Given EAB = 415V, assuming positive sequence, determine: vii: magnitude and angle of all phase voltages referred to the source terminals viii: magnitude and angle of all line currents flowing through the line impedances (Zline) ix: magnitude and angle of all phase currents flowing through the load impedances draw the phasor diagram showing the line and phase current relationship xi: magnitude and angle of all line voltages at each load xii: total apparent power, active power, and reactive power at the loads Zline = 0.2 + j0.4 Ω Load Impedance = 36 + j27 Ω Figure QI: Star Delta connection circuit for a three-phase system

Based on the circuit shown in Figure Q1, the star-connected three-phase supply is connected to balanced delta-connected loads. Given EAB = 415V, assuming positive sequence, determine:
vii: magnitude and angle of all phase voltages referred to the source terminals
viii: magnitude and angle of all line currents flowing through the line impedances (Zline)
ix: magnitude and angle of all phase currents flowing through the load impedances
draw the phasor diagram showing the line and phase current relationship
xi: magnitude and angle of all line voltages at each load
xii: total apparent power, active power, and reactive power at the loads
Zline = 0.2 + j0.4 Ω
Load Impedance = 36 + j27 Ω
