A simple power system is shown in this Fig. The generator (480 V, 10 kVA) is connected to an ideal step-up transformer (1:10), a transmission line (R=20 Ohm and X=60 Ohm), step down transformer (20:1) and a load with magnitude Z=10 Ohm and angle =30 degree  the base values for this system are chosen to be 480 V and 10 kVA at the generator. Calculate the 1/per-unit impedance of the load 2/per-unit current in the line
