Abstract :
This paper provides a step by step procedure for the computation of electromagnetic (EM) fields in the vicinity of power transmission lines. By decomposing the transmission line into a number of Hertzian dipoles, the electric and magnetic fields at any point above the ground can be found by summing up the contribution of each segment. Two analytical frequency-domain approaches for the calculation of radiation from a horizontal electric dipole (HED) located above a finitely conducting ground are implemented and compared. Numerical electromagnetic code (NEC-4) is used in order to verify the results.
