Abstract

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