"Reliable protection of buried telecommunication cables against the external electromagnetic fields (particularly from near overhead lines of high and very high voltages, traction trolley lines or high voltage cable networks) is one of the necessary conditions for correct design of the corresponding cable runs. The presented paper deals with improved methodology of evaluation of these influences, their compensation by means of various passive and active elements and other possibilities of their reduction to acceptable values. The theoretical analysis is supplemented with several illustrative examples and discussion concerning the values of reduction coefficients for dif-ferent kinds, materials and positions of the shielding elements." .
