MEASUREMENT FREQUENCY INFLUENCE ON THE INTERFERENCE DISTURBANCES NEAR THE EXTRA HIGH VOLTAGE LINES

SUMMARY The principal objective of this paper is to present a determination calculation program of the exact profile of the level of radionoise of existing lines E.H.V and on project according to the frequency. The method used for the determination of the disturbing field is an analytical method based on the theory of the modal propagation. We present a calculation program based on MATLAB with examples of real lines. Keyword: Interference disturbances, frequency, extra high voltage, modal propagation.
