Distributed vs. spot temperature measurements in dynamic rating of overhead power lines
TL;DR: Spot measurements are enough to obtain a good approximation of the average temperature of the line conductor in real-time monitoring of an overhead power line using a distributed temperature sensing system and are compared with spot temperature measurements to estimate the loss of accuracy of having less thermal information.
