Abstract :
In this paper, the basic concepts of dynamic thermal ratings of overhead transmission conductors are discussed. The sensitivity of these ratings with ambient conditions is evaluated. Innovative concepts in the measurement of overhead sag are given and correlated with dynamic rating of overhead transmission conductors. Dynamic transmission line thermal ratings take on increased importance in the deregulated electric power industry, since transmission capacity is sold as a deregulated commodity. Also, the electric utilities are under pressure to utilize all their transmission resources to the fullest
