1. Given a single phase, 138 kV, 60-Hz, 50 km-long transmission line consisting of two aluminum conductors with a 5 cm diameter separated by a spacing of 2 meters, calculate the following: Total series inductive reactance of the line in ohms. Recall, µo = 4x x 10-7H/m. 2. Using the line data in the previous problem, assume that the AC resistance of the line is 5% greater than its DC resistance and calculate the following: Total series impedance of the line in ohms. Note that aluminum has a resistivity of p= 2.83 x 10-8N – m.

Can you explain Question 2 please

1. Given a single phase, 138 kV, 60-Hz, 50 km-long transmission line consisting of two aluminum
conductors with a 5 cm diameter separated by a spacing of 2 meters, calculate the following:
• Total series inductive reactance of the line in ohms. Recall, µo = 47 x 10-7H/m.
2. Using the line data in the previous problem, assume that the AC resistance of the line is 5%
greater than its DC resistance and calculate the following:
• Total series impedance of the line in ohms. Note that aluminum has a resistivity of
p = 2.83 x 10-82 – m.
