电磁兼容性(EMC).第4-11部分:试验和测量技术.电压暂降、短时中断及电压变化抗扰度试验

[中文适用范围]： IEC 61000 的这一部分定义了连接到低压供电网络的电气和电子设备的电压暂降、短时中断和电压变化的抗扰度测试方法和首选测试级别范围。这个标准 [外文原描述]： This part of IEC 61000 defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. This standard applies to electrical and electronic equipment having a rated input current not exceeding 16 A per phase, for connection to 50 Hz or 60 Hz a.c. networks. It does not apply to electrical and electronic equipment for connection to 400 Hz a.c. networks. Tests for these networks will be covered by future IEC standards. The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to voltage dips, short interruptions and voltage variations. This second edition cancels and replaces the first edition published in 1994 and its amendment 1 (2000). This second edition constitutes a technical revision in which 1) preferred test values and durations have been added for the different environment classes; 2) the tests for the three-phase systems have been specified. It has the status of a Basic EMC Publication in accordance with IEC Guide 107. The contents of the interpretation sheet 1 of August 2010 have been included in this copy.
