Transmission Line Sag & Synchrophasors in ISACGrid

Electric transmission lines sag dangerously under heavy electrical loads and high ambient temperatures, causing catastrophic tree contact and wildfire ignition. ISACGrid turns power corridor wireless networks into precision radar that measures wire sag to within millimeters.
