Analysis of Different Dynamic Line Rating System Configurations in a Distribution Line

Different dynamic line rating systems have been developed for monitoring overhead lines. The aim of these systems is to estimate the actual rating of electric lines and use all the available capacity to achieve a more efficient use of the existing lines. Some systems have been installed in a distribution pilot line to evaluate the different uncertainty levels. Systems that measure weather parameters, conductor temperature and tension are assessed. The results show that in conductor temperature and tension based systems the uncertainty decreases as the conductor temperature increases.
