To guarantee the tensile strength and clearance requirements of transmission lines are not violated under time-varying external conditions, transmission lines are given line ratings that determine their maximum power-carrying capacities. Many utilities determine line ratings using approaches such as seasonal or static ratings. However, dynamic line ratings (DLRs) are rising in popularity as an innovative approach to evaluating the capacity of transmission lines by considering real-time weather conditions. Brian Berry reveals how to properly implement DLRs to ensure accurate ratings assessments. Read more in T&D World.
