IEC 61000-4-11:20 20作为IEC 61000-4-11:20 20 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 61000-4-11:20 20定义了连接到低压电源网络的电气和电子设备在电压骤降、短暂中断和电压变化时的抗扰度测试方法和首选测试水平范围。本文件适用于每相额定输入电流不超过16 A的电气和电子设备，用于连接到50 Hz或60 Hz交流网络。它不适用于连接到400 Hz交流网络的电气和电子设备。这些网络的测试将在未来的IEC文件中涵盖。本文件的目的是建立一个通用参考，用于评估电气和电子设备在遭受电压骤降、短暂中断和电压变化时的抗扰度。注1 IEC 61000-4-14涵盖了电压波动抗扰度测试。本文件中记录的测试方法描述了评估设备或系统对规定现象的抗扰度的一致方法。 注2如IEC指南107所述，这是供IEC产品委员会使用的基本EMC出版物。正如指南107中所述，IEC产品委员会负责确定是否应应用该抗扰度测试标准，如果应用，则负责定义适当的测试水平。技术委员会77及其小组委员会准备与产品委员会合作，评估其产品特定免疫测试的价值。这第三版取消并取代了2004年出版的第二版和修正案1:2017.本版构成技术修订。与上一版相比，此版本包括以下重大技术变更: -瞬变的上升时间和下降时间现在是条款3中定义的术语； -电压骤降和短暂中断的起源现在在第4条中陈述。 关键词:抗扰度测试方法,低压供电网络

IEC 61000-4-11:2020 is available as IEC 61000-4-11:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61000-4-11:2020 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 document 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 AC networks. It does not apply to electrical and electronic equipment for connection to 400 Hz AC networks. Tests for these networks will be covered by future IEC documents. The object of this document 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.
NOTE 1 Voltage fluctuation immunity tests are covered by IEC 61000-4-14. The test method documented in this document describes a consistent method to assess the immunity of equipment or a system against a defined phenomenon.
NOTE 2 As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and, if applied, they are responsible for defining the appropriate test levels. Technical committee 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products. This third edition cancels and replaces the second edition published in 2004 and Amendment 1:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- rise time and fall time of transients are now defined terms in Clause 3;
- the origin of voltage dips and short interruptions is now stated in Clause 4.
