Abstract
A system for generating line ratings includes a module for receiving data concerning a power line, a module for stores the data concerning said power line, and a module receives weather data associated with each of the geographic locations along the length of the power line. A processor is configured to select between generating a line rating based on the at least one tension/sag measurement and the weather data associated with each of said geographic locations along the length of said power line, where if the power line has a load exceeding a predetermined threshold, then the processor generates a line rating based on the at least one tension/sag measurement, and where if the power line has a load below the predetermined threshold, then the processor generates a line rating based on the weather data associated with each of the geographic locations along the length of the power line.
