Today we see in Asia how they clean VHV very high voltage by drones. What we see is Faraday cage principle and induction field circles being 90 deg shifted not to induce any voltage. Please see pic above ^^^ Now question: What do you await to be inducted in car on highway passing VHV columns? Yes, the same: Highway must be 90 deg shifted to wires of VHV :) Same principle if you create a cage of wires and you are protected like coax cable shield ;) Pic of coax shielding: Ah the question why they are cleaning VHV? Remeber the lecture about water as polar dissolvant. What is more Ice has a grid. Next realize this ice grid is shieding and the field is doing the work which is energy. Yes the losses of VHV wires per length are significant: R=ro*L/S and what is S? Area on this VHV wire? Yes: () And higher S area is lower R, and from P=U^2/R=UI we know current rises which is the fire on the VHV. In this equation I and /R are inequally measured or ratio_ed. But think twice what your Dad engineer told you: Why are we using Aluminium cable today, my son, nexgen engin? I'm tellin him yes, due to oxidation surfaces, aluminium is not oxiding that way as iron cables. Aluminium covers by THIN layer and STOPS OXIDING... Ah yes, lectures from chemistry 2002!
