A new 3 phase, 60 Hz transmission line is to be built using Falcon conductor. Falcon conductor has an outside diameter of 1.545 inches; stranding of 54/19 (A/St), which yields a GMR for the conductor of 0.0523 feet. Resistance at 60-Hz is 0.0612 /mile. The tower to be used has the three conductors in a horizontal configuration with the phase conductors 40 feet above the ground and spaced 20 feet apart (i.e., from left to center is 20 feet, center to right is 20 feet, and left to right is 40 feet). Fifteen feet above the phase conductors are two ground conductors, one 12 feet to the left of center and one 12 feet to the right of center. The ground wires use Partridge conductors, with an outsider diameter of 0.642 inches and a GMR of 0.0217 feet. Resistance at 60-Hz is 0.350 /mile. Assume ground resistivity of 100 -m
