电磁兼容性（EMC） 第 5-1 部分：安装和缓解指南 一般注意事项

[中文适用范围]： 本部分IEC 61000-5的技术报告涵盖了确保工业、商业和住宅设施中使用的电气和电子设备或系统之间电磁兼容性(EMC)的缓解方法的一般考虑和指南。本文件适用于所有使用和安装敏感电气或电子设备和系统以及具有高发射水平的设备的用户和安装人员，这些设备可能降低整体电磁(EM)环境。它主要适用于新安装，但也适用于旧安装的修改或增强。 [外文原描述]： IEC TR 61000-5-1:2023 which is a technical report, covers general considerations and guidelines on mitigation methods aimed at ensuring electromagnetic compatibility (EMC) among electrical and electronic apparatus or systems used in industrial, commercial, and residential installations. This document is intended for use by all using and installing sensitive electrical or electronic installations and systems, and equipment with high emission levels that could degrade the overall electromagnetic (EM) environment. It applies primarily to new installations, but also applies during modifications or enhancements of legacy installations. Specific topics, such as recommendations on the design and implementation of the earthing system, including the earth electrode and the earth network, the design and implementation of bonding apparatus or systems to earth or to the earth network, the selection and installation of appropriate cables, and the design and implementation mitigation means involving shielded enclosures, high-frequency filters, isolating transformers, surge-protective devices, etc., will be addressed in other parts of IEC 61000-5. Within this document the fundamental measures will be described. The practices presented in this document address the EMC concerns of the installation, not the safety aspects of the installation nor the efficient transportation of power within the installation. Nevertheless, these two prime objectives are taken into consideration in the technical observations concerning EMC. These two primary objectives can be implemented concurrently for enhanced EMC of the installed sensitive apparatus or systems without conflict by applying the practices presented in this document and the relevant safety requirements. It is the responsibility of the designer and the installer to select the relevant technique most appropriate to a particular installation. This second edition cancels and replaces the first edition published in 1996. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a. restructuring of clauses and subclauses with amending of technical content; b. alignment of the terminology with other parts of the IEC 61000 series, for example with IEC TR 61000-2-5; c. addition of an overview regarding the IEC 61000-5 series in Annex A.
