Line configuration for

Problem 4.25

For the overhead line of configuration shown in Figure 4.33, operating at 60 Hz, and

a conductor temperature of 70°C, determine the resistance per phase, inductive re-

actance in ohms/mile/phase and the current carrying capacity of the overhead line.

The resistance of each conductor in the four-conductor bundle is 0.12 22/mi.
