d) A transmission line designed for power transmission at 60 Hz is made with superconducting cables. The two conductors that make the transmission line are separated by 3 m. The size of the wires is not known, but their inductance per unit length is 0.5 μΗ/m. The permittivity and permeability are those of free space and the conductivity of air is 10-7 S/m. Calculate: The attenuation constant of the line. ii) The characteristic impendence of the line. d) A transmission...
A.)Engineers are tasked with calculating the dimensions of a transmission line from a power plant to a city 100 km away. The power plant outputs 765,000 V, and the transmission line must transport a minimum of 500,000 A of current. An intern looks up the value of resistivity from a database with the value of ?=1.29 ×10−8 Ω?. What is the diameter the wire the engineers need to use? Show work. B.) The intern was in the wrong database and...
