A 500-kV, 60 Hz, three-phase completely transposed overhead linehas three ASCR 1113-kcmil conductors per bundle, with 0.5 m betweenconductors in the bundle. The horizontal phase spacing betweenbundle centers are 10, 10, and 20 m. With a length of 190 km, theline delivers 1800 MW at 475 kV and at 0.90 power factor leading tothe receiving end at full load. Using the nominal π circuit,calculate the: (a) ABCD parameters, (b) sending-end voltage andcurrent, (c) sending-end power and power factor, and (d) the fullload line losses and efficiency. Assume a 50 ̊C conductortemperature to determine the resistance of this line.
