标准摘要
[中文适用范围]： 本部分IEC 61000涉及设备产生的电压变化、电压波动和闪烁对公共低压供电系统的影响。它规定了在特定条件下测试的设备产生的电压变化限制。本文档主要适用于额定输入电流从16A到75A（包括75A）的电气和电子设备，这些设备旨在连接到标称系统电压在220V至250V之间、线对中性点为50Hz的公共低压配电系统，并且需要条件连接。本文档也适用于IEC 61000-3-3范围内的设备，当使用参考阻抗Zref测试或评估时不符合限制，因此需要条件连接。符合IEC 61000-3-3要求的设备不包括在本部分IEC 61000中。根据本文档进行的设备测试是类型测试。 [外文原描述]： IEC 61000-3-11:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61000-3-11:2017 is concerned with the emission of voltage changes, voltage fluctuations and flicker produced by equipment and impressed on the public low-voltage supply system. It specifies the limits of voltage changes produced by equipment tested under specified conditions. This edition includes the following significant technical changes with respect to the previous edition: a) addition of a new Annex A which explains the limitations and effectiveness of IEC 61000‑3-11 regarding the connection of multiple items of similar equipment at the same location in the supply network.
