A new 3 phase, 60 Hz, 200 mile transmission line is to be built using Bluebird conductor. Bluebird conductor has an outside diameter of 1.762 inches; stranding of 84/19 (Al/St) yields a GMR for the conductor of 0.0588 feet. Resistance for each conductor is 0.0505 ?/mile. Bundling is to be used, with the three conductors per phase spaced symmetrically 1 feet apart. A horizontal tower configuration is used, with a distance of 20 feet between adjacent phases (i.e., 20 feet between the left and center phases, 20 feet between the center and right phases, and hence 40 feet between the left and right phases). Assuming that the line is uniformly transposed, draw the medium length ?-equivalent circuit for the line, showing the value of all parameters. For reference ?0 = 4? x 10-7 H/m and ?0
= 8.854 x 10-12 F/m. There are 1609 meters per mile.
