IEC TR 61000-3-18:20 24是一份技术报告，报告了调整IEC 61000-3-2和IEC 61000-3-12中IEC设备排放限值的方法的开发情况，以用于这些文件未涵盖的地区。它确定了现有设备排放限值标准在国际适用性方面的差距，并确定了对谐波电压性能评估重要的公共电力系统特性。在特定地区调整上述IEC设备谐波排放标准的目的是在这些地区的公共电力系统中保持每相高达75 A的设备的相似电磁兼容性（EMC）。笔记？不同国家不同电压等级之间的界限不同（参见IEC 60050？601:1985,601-01-28).本文档在提及50 Hz和60 Hz系统电压时使用以下术语:-低压(LV)是指Un≤1kV；-中压(MV)是指1kV

IEC TR 61000-3-18:2024 which is a technical report, reports on the development of a methodology for adapting IEC equipment emission limits from IEC 61000-3-2 and IEC 61000-3-12 for use in regions not covered by these documents. It identifies gaps in the existing equipment emission limit standards concerning their international applicability and identifies public power system characteristics important for the evaluation of harmonic voltage performance. The purpose of adapting the above-mentioned IEC equipment harmonic emission standards in a particular region is to maintain similar electromagnetic compatibility (EMC) of equipment up to 75 A per phase in the public power systems in those regions.
NOTE？The boundaries between the various voltage levels differ amongst different countries (see IEC 60050？601:1985, 601-01-28). This document uses the following terms when referring to 50 Hz and 60 Hz system voltages:
- low voltage (LV) refers to Un ≤ 1 kV;
- medium voltage (MV) refers to 1 kV < Un ≤ 35 kV;
- high voltage (HV) refers to 35 kV < Un ≤ 230 kV.
EMC requirements can have economic and societal impacts; these have not been considered in the development of this document. The consideration of these factors generally occurs in the technical committees working on development and maintenance of emission limit standards.
