1. A 60 HZ single phase, two wire overhead line has solid cylindrical copper conductors with 1.5cm diameter. The conductors are arranged in horizontal configuration with 0.5m spacing.Calculate in mH/km:
a.)The inductsnce f each conductor due to internal flux linkages only.
b.) The inductance of each conducordue to both internal and external flux linkages.
c)The total inductance of the line.
2. Rework problem 1 if the diameter of each conductor is:
a.)Increased by 20% to 1.8cm.
b.) Decreased by 20% to 1.2cm, without changing the phase spacing.
Compare the results with thoseof problem 1.
