The figure below shows the one-line diagram of a power system. The three-phase power and line-line ratings are as follows: X = 12 % 18/270 KV X = 8 % G: 80 MVA 20 KV T: 60 MVA T2: 70 MVA 250/20 KV X = 10 % Line: Z = 45 + j 225 a 280 KV The loads are: Sz = 60 MVA, 0.75 power factor lagging at 320 KV. S2 = 60 MVA, 0.75 power factor lagging at 23 KV. T V, Lin
