10-7. Figure P10-2 shows a one-line diagram of a three-phase power system. The ratings of the various components in the system are:

Synchronous Generator 1:	40 MVA, 13.8 kV, R = 3%, X_S = 80%
Synchronous Motor 2:	20 MVA, 13.8 kV, R = 3%, X_S = 80%
Synchronous Motor 3:	10 MVA, 13.2 kV, R = 3%, X_S = 100%
Y-Δ Transformers:	20 MVA, 13.8/138 kV, R = 2%, X = 10%
Line 1:	R = 10 Ω, X = 50 Ω
Line 2:	R = 5 Ω, X = 30 Ω
Line 3:	R = 5 Ω, X = 30 Ω

The per-unit system base for this power system is 40 MVA, 128 kV in transmission line 1. Create the per-phase, per-unit equivalent circuit for this power system.
