1 5.18 Draw an impedance diagram for the system whose one-line diagram is shown in Figure P5.18. The 30 and line-line ratings are as follows: Generator G: 15 MVA, 13.8 kV,

X = 0.15 p.u. Motor M1: 5 MVA, 13.8 kV, X = 0.15 p.u. Motor M2: 5 MVA, 14.4 kV, X = 0.15 p.u. T₁:25 MVA, 13.2 - 161 kV, X = 0.1 p.u. T₂: 15 MVA, 13.8 161 kV, X = 0.1 p.u. Line: /1000 (actual) Select a base of 100 MVA and 161 kV in the transmission line. T₁ JANU Line 000 M₁ M₂ Figure P5.18
