This part of CISPR 18, which is a technical report, applies to radio noise from overhead power
lines and high-voltage equipment which may cause interference to radio reception. The scope
of this publication 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 broadcast services.
The frequency range covered is 0,15 MHz to 300 MHz.
Radio frequency interference caused by the pantograph of overhead railway traction systems
is not considered in this technical report.
