Wind Speed Effect on the Conductor Temperature of a Distribution Line

Actual rating of the lines is important information for system operators. Dynamic line rating systems provide this information. The ampacity of the line it is related to the conductor temperature. This temperature can be calculated from meteorological measurements or by means of a Temperature Measurement System. Three different weather monitoring systems and one Temperature Measurement System have been installed along an overhead power line. These systems allow quantifying the uncertainty due to the spatial variability.
