1. A 60 Hz, 765 kV three-phase overhead transmission line has four ACSR 1113 kcmil 54/3 conductors per phase. Determine the 60 Hz resistance of this line in ohms per km per phase at 50o C. (0.0151 ohms/km per phase)
2. A 7 kV 60 Hz single phase two-wire overhead line has 1/0 copper conductors with 1 m horizontally between conductors. Calculate R (0.607 ohms/mile) and L (2.274 uH/m).
3. A 12 kV 60 Hz three-phase three-wire overhead line has Drake ACSR conductors spaced 4 ft apart in an equilateral triangle. Calculate R (0.1288 ohms/mile) and L (0.9339 uH/m)
4. A 230 kV, 60 Hz, three-phase transposed overhead transmission line has one ACSR 954 kcmil conductor per phase and flat horizontal spacing with 8 m between adjacent conductors. Determine the inductance in H/m and the inductive reactance in ohms/km (1.3 uH/m, 0.506 ohms/km).
