Abstract

This paper considers the influence of changes in the transmission line permissible load current depending on conductor and ambient temperatures, the climate conditions. The theoretical background of the load current calculation method with heating limitation is proposed. The simulation tasks were based on specific data information of existing overhead lines of the Latvian power system. Moreover, a special thermovision device was used for precise determination of conductor temperature. The results of the received data are presented.
