标准摘要
[中文适用范围]： 本部分 IEC 61000 适用于测量叠加在 50 Hz 和 60 Hz 供电系统基波上的频率范围高达 9 kHz 的频谱分量的仪器。出于实际考虑，本标准区分了谐波、间谐波以及高于谐波频率范围直至 9 kHz 的其他分量。本标准定义了用于根据某些标准（例如 IEC 61000-3-2 中给出的谐波电流限值）测试单个设备以及测量实际供电系统中的谐波电流和电压的测量仪器。高于谐波频率范围直至 9 kHz 的测量仪器被临时定义（见附录 B）。注 1：本文件详细处理基于离散傅里叶变换的仪器。注 2：本标准中测量仪器的功能和结构描述非常明确，应按字面意思理解。这是由于需要有参考仪器，无论输入信号特性如何，都能产生可重复的结果。注 3：该仪器定义为可测量高达 50 次谐波的谐波。 本部分 CEI 61000 适用于测量叠加在 50 Hz 和 60 Hz 供电系统基波上的频率范围高达 9 kHz 的频谱分量的仪器。出于实际考虑，本规范区分了谐波、间谐波以及高于谐波频率范围直至 9 kHz 的其他分量。本规范定义了用于根据某些规范（例如 CEI 61000-3-2 中给出的谐波电流限值）测试单个设备以及测量实际供电系统中的谐波电流和电压的测量仪器。高于谐波频率范围直至 9 kHz 的测量仪器的定义在附录 B 中讨论。注 1：本文件详细处理基于离散傅里叶变换的仪器。注 2：本规范中测量仪器的功能和结构描述非常明确，应按字面意思理解。这是因为需要有参考仪器，无论输入信号特性如何，都能产生可重复的结果。注 3：该仪器定义为可测量高达 50 次谐波的谐波。 [外文原描述]： IEC 61000-4-7:2002+A1:2008 applies to instrumentation intended for measuring spectral components in the frequency range up to 9 kHz which are superimposed on the fundamental of the power supply systems at 50 Hz and 60 Hz. For practical considerations, this standard distinguishes between harmonics, interharmonics and other components above the harmonic frequency range, up to 9 kHz. Defines the measurement instrumentation intended for testing individual items of equipment in accordance with emission limits given in certain standards (for example, harmonic current limits as given in IEC 61000-3-2) as well as for the measurement of harmonic currents and voltages in actual supply systems. The contents of the corrigendum of July 2004 have been included in this copy. This consolidated version consists of the second edition (2002) and its amendment 1 (2008). Therefore, no need to order amendment in addition to this publication.
