1.Draw an Impedance & Reactance diagram for the electric power system shown in figure showing all the impedances in per unit. Choose the generator as the base The three- phase and line- to- line ratings are given below
G :100 MVA, 20 KV , X = 9%
T1: 90 MVA, 20/200 KV, X=15%
T2: 90 MVA, 200/20 KV, X=20%
M : 90 MVA, 18 KV, X= 8%
Line : 200 KV, X=120 Ω
