适用范围:This part of CISPR 18, which is a technical report, applies to radio noise from overhead powerlines and high-voltage equipment which may cause interference to radio reception.The frequency range covered is 0,15 MHz to 300 MHz.A general procedure for establishing the limits of the radio noise field from the power linesand equipment is recommended, together with typical values as examples, and methods ofmeasurement.The clause on limits concentrates on the low frequency and medium frequency bands and it isonly in these bands where ample evidence, based on established practice, is available. Noexamples of limits to protect radio reception in the frequency band 30 MHz to 300 MHz havebeen given, as measuring methods and certain other aspects of the problems in this bandhave not yet been fully resolved. Site measurements and service experience have shown thatlevels of noise from power lines at frequencies higher than 300 MHz are so low thatinterference is unlikely to be caused to television reception.The values of limits given as examples are calculated to provide a reasonable degree ofprotection to the reception of broadcasting at the boundary of the recognized service areas ofthe appropriate transmitters in the radio frequency bands used for a.m. broadcasting, in theleast favourable conditions likely to be generally encountered. These limits are intended toprovide guidance at the planning stage of the line and national standards or otherspecifications against which the performance of the line may be checked after constructionand during its useful life.The measuring apparatus and methods used for checking compliance with limits shouldcomply with the respective CISPR specifications, as e.g. the basic standards series CISPR 16,see [1]*.2 Normative referencesThe following referenced documents are indispensable for the application of this document.For dated references, only the edition cited applies.
