2. A 70-mile, 60 Hz, single-circuit, three-phase line composed of Ostrich conductors with outside diameter equals 0.68 inch is arranged in flat horizontal spacing with 15 feet between adjacent conductors. The conductor resistance is 0.3372 ohms per phase per mile at 50C. The line delivers a load of 60 MW at 230 kV with 0.8 power factor lagging. Use a base of 230 kV, 100 MVA to: a) Determine the series impedance and the shunt admittance and the generalized circuit constants ABCD of the line (10 pts) b) Calculate the voltage, current, real and reactive power at the sending-end (10 pts] c) Calculate the efficiency of the line (5 pts) 2.
