电磁兼容性(EMC).第4-8部分:试验和测量技术.工频磁场抗扰度试验

[中文适用范围]： 本部分 IEC 61000 涉及设备在运行条件下对 50 Hz 和 60 Hz 工频磁干扰的抗扰度要求，相关场景包括：住宅和商业场所；工业装置和发电厂；中压和高压变电站。本标准的适用性取决于第 4 章规定的现象是否存在。本标准不考虑电缆或其他场安装部件的电容或电感耦合引起的干扰。其他处理传导干扰的 IEC 标准涵盖了这些方面。本标准的目的是为评估家用、商业和工业应用的电气和电子设备在承受工频磁场（连续和短时场）时的性能，建立一个共同且可重复的基础。该标准定义了：推荐的测试等级；测试设备；测试设置；测试程序。 [外文原描述]： 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.
