A 100-mi, single-circuit, three-phase transmission line delivers 55 MVA at 0.8 power-factor lagging to the load at 132 kV (line to line). The line is composed of Drake conductors with flat horizontal spacing of 11.9 ft between adjacent conductors. Assume a wire temperature of SC. Determine (a) The series impedance and the shunt admittance of the line. (b) The ABCD constants of the lint. (c) The sending-end voltage, current, real and reactive powers, and the power factor. (d) The percent regulation of the line.
