电磁兼容性（EMC）第4-8部分：测试和测量技术工频磁场抗扰度测试

[中文适用范围]： IEC 61000-4-8:2009 RLV 包含国际标准及其红线版本。 Redline 版本为您提供了一种快速、简单的方法来比较该标准与其先前版本之间的所有更改。 Redline 版本不是正式的 IEC 标准，只有当前版本的标准才被视为正式文件。 IEC 61000-4-8:2009 涉及仅在运行条件下设备对电源频率 50 Hz 和 60 Hz 的磁干扰的抗扰度要求，涉及： - 住宅和商业场所； - 工业装置和发电厂； - 中压和高压变电站。 IEC 61000-4-8:2009 对安装在不同位置的设备的适用性取决于现象的存在，如第 4 章中所规定。本标准不考虑由于电缆或设备其他部分中的电容或电感耦合而产生的干扰。现场安装。其他处理传导骚扰的 IEC 标准涵盖了这些方面。 IEC 61000-4-8:2009 的目标是建立一个通用且可重复的基础，用于评估家用、商业和工业应用的电气和电子设备在工频磁场（连续和短时场）下的性能。 IEC 61000-4-8:2009 定义： - 推荐的测试级别； - 测验设备; - 测试设置； - 测试程序。第二版取消并取代了 1993 年出版的第一版及其修正案 1 (2000)。它形成了技术修订。相对于前一版本，此版本包括以下重大技术更改：范围扩大到涵盖 60 Hz。修订了测试发生器和相关感应线圈的特性、性能和验证。测试设置 (GRP) 和测试程序也进行了修改。 IEC 61000-4-8:2009 具有符合 IEC 指南 107 的基本 EMC 出版物的地位。电磁兼容；智慧城市 [外文原描述]： IEC 61000-4-8:2009 RLV contains the International Standard and its Redline version. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document. IEC 61000-4-8:2009 relates to the immunity requirements of equipment, only under operational conditions, to magnetic disturbances at power frequencies 50 Hz and 60 Hz related to: - residential and commercial locations; - industrial installations and power plants; - medium voltage and high voltage sub-stations. The applicability of IEC 61000-4-8:2009 to equipment installed in different locations is determined by the presence of the phenomenon, as specified in Clause 4. This standard does not consider disturbances due to capacitive or inductive coupling in cables or other parts of the field installation. Other IEC standards dealing with conducted disturbances cover these aspects. The object of IEC 61000-4-8:2009 is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment for household, commercial and industrial applications when subjected to magnetic fields at power frequency (continuous and short duration field). IEC 61000-4-8:2009 defines: - recommended test levels; - test equipment; - test set-up; - test procedure. This second edition cancels and replaces the first edition published in 1993 and its Amendment 1 (2000). It forms a technical revision. This edition includes the following significant technical changes with respect to the previous edition: the scope is extended in order to cover 60 Hz. Characteristics, performance and verification of the test generator and related inductive coils are revised. Modifications are also introduced in the test set-up (GRP) and test procedure. IEC 61000-4-8:2009 has the status of a basic EMC publication in accordance with IEC Guide 107.
