Abstract :
A finite difference method is used in the simulation of underground power cable systems. Realistic assumptions and configurations of cable installations, including multi-layers of nonhomogeneous soils, are considered. The model used has been previously introduced for only one cable in the trench. New modifications have been added to accommodate two cables with variable diameters located randomly in the trench. Two practical applications are considered; determining the effect of the variation of the cables´ diameters on the heat dissipation and the effect of cable spacing on the ampacity of the cables
