ABSTRACT:
A system for determining the sag of an overhead power transmission line to prevent flashover to adjacent objects on earth. A small replica of the transmission line conductor is provided and located in proximity to the transmission line. The temperature of the replica is measured along with the ambient temperature. By appropriate calculations, the ampacity determination is made to determine the maximum permitted current through the transmission line under the particular weather conditions.
