Dynamic (electrical overhead-)line rating is a great opportunity for transmission line operators (any voltage from 15 kV to 735 kV and over). It has been studied for more than 20 years inside CIGRE and IEEE working groups.

Navigation charts at a scale of 1:50,000 or smaller (1:100,000 is a smaller scale than 1:50,000) use the Mercator projection, and have since at least the 1930s. [ 29 ] [ 30 ] The Mercator projection has the property of maintaining angles correctly, so that a line on the earth's surface that crosses all the meridians at the same angle (a rhumb ...
The first would electrify the heavy-rail line and provide a short spur-line to central Port Adelaide (Port Dock). The option would convert the line to light rail and add a new on-street branch to Semaphore; a light rail conversion would also require the conversion or closure of the Grange line, and several options for the future of that line ...
