I need help working this one out. Would really appreciate the help.
A 3-phase, Δ-connected source has an internal impedance of 0.9 + 9j Ω/phase. The terminal voltage is equal to 13,200 Volts when no load is connected. The generator feeds a Δ-connected load with a per-phase impedance of 645 + 171j Ω/phase. The impedance of the transmission line connecting the generator to the load is 0.7 + 3j Ω/phase. The a-phase
internal voltage of the generator has been specified as the reference.
a) Construct a single phase equivalent circuit of the 3-phase system
b) Calculate the line currents: laA, IbB, and IcC
c) Calculate the magnitude of the line voltages at the terminals of the load
d) Calculate the magnitude of the line voltages at the terminals of the source
e) Calculate the magnitude of the phase current in the load
