The scope of this document includes the causes, measurement and effects of radio interference, design aspects in relation to this interference, methods and examples for establishing limits and prediction of tolerable levels of interference from high voltage overhead power lines and associated equipment, to the reception of radio signals and services. The frequency range covered is 0,15 MHz to 3 GHz. Radio frequency interference caused by the pantograph of overhead railway traction systems is not considered in this document. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - updated description of the RF characteristics of spark discharges which might contain spectral radio noise components up to the GHz frequency range; - addition of state of the art in HVDC converter technology Keywords: radio noise from overhead power lines and high-voltage equipment
