  • Adiabatic heating of bare conductors of overhead transmission lines with consideration of temperature dependent physical magnitudes
    Jakl, Franc ...
    The paper analyses a methodological approach to the issue as proposed by the CIGRE working group WG 22.12 Electrical Aspects of Overhead Lines of the CIGRE Study Committee SC22 Overhead Lines. ... Presented are the most appropriate methods for the calculation of conductor temperatures under nonstationary conditions at the occurrence of short circuit. It shows results of temperature calculations at adiabatic heating for the worst short-circuit case taking place in the electric power system in the duration of one second on different conductors and ground wires including OPGW cables with consideration of temperature dependent physical magnitudes i.e. for the specific heat of conductors with indication of values from laboratory tests.
