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...
