This work investigates the lateral profile of the electric field, the magnetic field, the audible noise and the radio interference generated by 138, 230 and 345 kV transmission lines in order to evaluate the influence of parameters (tower height, conductor type, relationship between weights span and winds span, distance between phases, arrangement, line type conventional and compact, number of circuits, number of conductors per phase and sag) in their right of way. The cables swing due the wind and the electromagnetic effects (using line design information) are considered. The minimum right of way necessary for the transmission lines is evaluated. The right of way calculation is based on equations of the electromagnetic theory and on the action of the wind causing the swing of the cables. The lateral profile electromagnetic effects and the right of way for different parameters of lines are presented. The results are compared with the right of way generally used by power utilities on the light of the present regulations.
