Sažetak

The present work includes the coupled electromagnetic/thermal analysis of a three-phase system composed of three single-core cables in trefoil configuration. The cable system is analyzed in thermally stationary and non-stationary state, taking into account the non-linearity of heat conduction in the soil surrounding the cable. The complex model of heat transfer in soil, caused by soil drying in the cable’s surrounding, has been made by applying two zones of different heat conductions.
