Abstract
This paper is dealing with the environmental
effects of extra high voltage
transmission lines.
A comprehensive view about the frequency
spectrum and the attenuation law of
radio interference and limit for good
weather are given.
The audible noise measurements
comprise the whole audible frequency range.
The analises were made by octave and by
narrow band filtering.
The problem of measurement of electric
field strength and results of tests carried
out beneath EHV lines and in substation are
reported. The currents induced in humans
and vehicles are determined.
