1. 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. Calculate the impedance to neutral of this line. Calculate the line charging current in A/phase if the line is 100 km long and is operated at line-line voltage of 230 kV (8.565 pF/m, j3.23 micro-Siemens/km, 42.9 A/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 C and capacitive reactance. (5.184 pF/m, 5.117x108 m-ohm)

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 C and capacitive reactance. (12.47 pF/m, 2.127x108 m-ohm)
