Abstract
In this contribution a dynamic thermal analysis of an overhead transmission line and a buried power cable is presented. The temperature is calculated as a function of time using a realistic power input obtained from field data measurements. For both the temperature and the power a harmonic analysis is performed. The phase shift between the Fourier components corresponding to a one day period turns out to be a good indication of the temperature delay time with respect to the power peaks. In order to validate and assess the proposed method a lab experiment has been conducted.
