Question:
A 15 -km-long, \(230 \mathrm{kV}\) aluminum transmission line delivers 34 MW to a city. If we assume a solid cylindrical cable, what minimum diameter is needed if the voltage decrease along this run is to be no more than \(1.0 \%\) of the transmission voltage? The resistivity of aluminum is \(2.7 \times 10^{-8} \Omega \cdot \mathrm{m}\).
