In all honesty I have no clue how to even approach this...
A generator is connected to a high voltage line through a Δ-Y step-up transformer T1
A Y-Δ step-down transformer T2 is connected at the receiving end of the line to supply a motor load. The rating details are as follows:
Generator: 30 MVA, 13.8 kV, XG = 0.10 p.u.
Motor: 20 MVA, 13.8 kV, XM = 0.08 p.u.
Transformer T1: 20 MVA, 13.2 -132 kV, XT1 = 0.10 p.u.
Transformer T2: 15 MVA, 13.8-138 kV, XT2 = 0.12 p.u.
Transmission Line: ZTL = j100 ohms (actual
Use 30 MVA as the base and draw an equivalent circuit (impedance) diagram showing the individual per unit values. What is the magnitude of load current in the motor?
