标准摘要
[中文适用范围]： IEC 61000的第这一部分涉及由设备产生并施加到公共低压供电系统上的电压变动、电压波动和闪变的发射。它规定了在 specified conditions 下测试的设备产生的电压变动限值。本文件主要适用于额定输入电流从 16 A 到包括 75 A 的电气和电子设备，这些设备设计用于连接到公称系统电压在 220 V 至 250 V（线对中性点）、频率为 50 Hz 的公共低压配电系统，且受条件连接约束。本文件也适用于 IEC 61000-3-3 范围内的设备，当这些设备在使用参考阻抗 Zref 进行测试或评估时不符合限值，因此受条件连接约束。符合 IEC 60050-161 要求的设备被排除在本部分 IEC 61000 之外。根据本文件进行的设备测试为型式试验。 [外文原描述]： 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.
