ABSTRACT. – Emissions of pollutants and air quality in the area of influence of high voltage overhead electrical lines. This paper presents some theoretical and experimental considerations regarding to the impact of energy fluxes that pass through the conductors of high voltage aerial electrical lines (> 110kv) on the environment. Overhead high voltage lines generating air pollution by ozone and nitrogen oxides as a result of corona discharges occurring around active conductors, especially during humid weather. Experimental measurements performed using a test van equipped with analyzers and weather station have shown the difference regarding the concentration of pollutants (emissions) that exists in the lines of high voltage and level of the concentrations outside the area of influence of high voltage power lines.
Keywords: ozone, nitrogen oxides, corona effect, air pollution, emissions.
