In electricity transmission system, the overhead conductors gets heated and cooled due to heat transmissiondepending on weather parameters at the particular location and the current passing through it. The temperature fluctuationsaffect the conductors by limiting the maximum current capacity of the conductor, inducing thermal stresses in it which cancreates sag of the line, which in turn, reduces the ground clearance and degrading the mechanical properties of theconductor. Therefore, CIGRE (Conseil International des Grands Réseaux Électriques), an organization in the field of highVoltage electricity has proposed a thermodynamic model[1,2] for determining the temperature of the conductordynamically. This model can be used in DLRS(Dynamic Line Rating Scheme) in which real time monitoring of temperature isdone to optimize current according to it. In order to design a dynamic rating scheme, utilities need to know what is theaccuracy of the thermodynamic model of the transmission line. In present study, the CIGRE model is analyzed with the helpof Matlab software by calculating the hourly temperature of ACSR Zebra conductor and the results are validated bydetermining the temperature of an actual transmission line.
