The developed computational model is intended to determine and analyze the three-dimensional magnetic field of underground cable lines with the magnetic shields of a limited length used to reduce the field on the ground. For example, the part of soil which is magnetic composite medium around the cable line can be considered as the magnetic shield. The mathematical model was tested by comparison of computational results with the data obtained by analytical expression. The numerical results show that the magnetic field on the ground over the cable line is reduced almost 4 times when the magnetic permeability of the shield as magnetic composite filling soil is μr ≥100. References 8, figures 2.
Key words: underground cable line, magnetic shield, filling soil, magnetic composite material, magnetic field, three-dimensional computer modeling.
