three-phase 60Hz line with a flat horizontal spacing uses conductors with a GMR of 0.0112 m, diameter of 3.4 cm, and a spacing between adjacent conductors of 11 m. The inductive reactance per phase in ohms per kilometer is what?

Three conductors of a 3-phase overhead line are arranged in a horizontal plane in the order a-b-c, distance between a and b is 12 m, b and c is spaced 12 m apart. The diameter of each line conductor is 2 cm. Calculate the Capacitance per phase per km (C1) for this arrangement. Calculate Capacitance per phase per km(C2) if the spacing between the conductors are reduced by 1/4th of the given spacing.  Capacitance in  per Phase per Km for Arrangement 1 (C1) Capacitance in   per phase per km for Arrangement 2 (C2)

The Cost OF Single phase overhead feeder is OMR q Per KM(a is area of cross section in sq mm) and the intrest and depre Ciation Chargs onfeeder omical carrent density are 7Y. defermain to use for the most econor requiring Full load current of 27% of the 12 baisa is year. The Cost per unit ass ume resistance of Im lenahth length and I mm² secfion of Conductor as 1/32 find Current densi ty =?

Q2(a) Figure Q2(a) shows the spacing of a double circuit 3-phase overhead line. The phase sequence is UVW and the line is completely transposed. i) Critically assess the advantages of double circuit line over single circuit line Calculate the inductance per phase for 500 meter length of line using Table 2(a) data for the Figure Q2(a).
