An overhead 3- phase transmission line has a conductor of section 90 mm and effective diameter of 1cm and is placed at the vertices of an equilateral triangle of side 1 metre. The line is 20 km long and delivers a load of 10MW at 33KV and power factor of 0.8 lagging .Neglect capacitance of the line and assumes that at a temperature of 200 C. the resistance of copper of 1mm-is 1 580 per metre when the section is 1mm2. Use the above information to answer Q46 to Q50.

In a 10 km long three phase line the diameter of the conductor is 25 mm hence the conductors are symmetrically arranged with a space of 2 m.So find the capacitance per phase.

For the Figure 9 shown: A 273 -km long, 47 Hz, three-phase, transmission line is composed 2 parallel lines. The conductors in the lines are stranded with GMR of 13.59 -mm each. If the distance D in the figure is 4.78 m., What is inductive reactance per line in (ohm)? Figure 9 b D 1.732D 2D 1.732D 1.732D D b' 3 1.732D
