Problem 1: AAC aluminum stranded conductor as Hawkweed type is composed of 24 aluminun wires with diameter line of each as 0.1118 inch. In data sheet from manufacturer stated that a conductor cross-sectional area is 300,000 cmil. For this conductor: a. Determine total cross- sectional area in numerical calculation and compare percent deviation from manufacture. b. Verify the dc resistance of this conductor at 50°C of 0.21330/mi, when the resistivity of the conductor (p) is 11.88 N-cmil/ft. Assuming that a 2% increase in resistance due to spiraling. c. Determine percent decrease in resistance at 60 Hz at 25° if the resistance at 50° is 0.2108 2/mi, when temperature constant T of copper is 228.
