Description
  • The paper is focused on evaluation of the thermal model of a transmission overhead line and its comparison with measured values using two different techniques. The most problematic part of the model development was to reliably respect convective cooling of the conductor. A confrontation of several ways of convection calculation was made using CFD and two correlation methods. The deviation of modeled temperature was mostly ?1 °C in the case of surface temperature measurement. Difference between surface and conductor core temperature is depicted and statistically evaluated.
