IEC 61000-4-30:2015+A1:2021定义了交流电能质量参数结果的测量和解释方法。声明基频为50 Hz或60 Hz的电源系统。每个相关参数的测量方法都以给出可靠和可重复的结果的术语进行描述，而不管方法的实施方式如何。本标准涉及现场测量的测量方法。本标准涵盖的参数测量仅限于电力系统中的传导现象。本标准中考虑的电能质量参数包括电源频率、电源电压大小、闪烁、电源电压骤降和骤降、电压中断、瞬态电压、电源电压不平衡、电压谐波和间谐波、电源电压上的市电信号、快速电压变化和电流测量。附件C（信息性）考虑了2 kHz至150 kHz范围内的发射，附件D（信息性）考虑了偏差过大和过小。根据测量的目的，可以测量该列表中的所有现象或现象的子集。这第三版取消并取代了2008年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: -目前的测量方法，以前是信息性的，现在是规范性的，但有一些变化； -增加了RVC（快速电压变化）的测量方法； -在资料性附件C中增加了2 kHz至150 kHz范围内传导发射的测量方法； -偏差不足和偏差过大参数移至资料性附件D；-定义并澄清了A类和S类测量方法，而B类被移至资料性附件E，并考虑将来删除； -测量方法在本标准中继续，但影响量、性能和测试程序的责任转移到IEC 62586-2。 2016年12月更正的内容已纳入本副本。 该合并版本由第三版（2015年）及其修正案1（2021年）组成。因此，除本出版物外，无需下令修订。

IEC 61000-4-30:2015+A1:2021 defines the methods for measurement and interpretation of results for power quality parameters in a.c. power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz. Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the method's implementation. This standard addresses measurement methods for in-situ measurements. Measurement of parameters covered by this standard is limited to conducted phenomena in power systems. The power quality parameters considered in this standard are power frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells, voltage interruptions, transient voltages, supply voltage unbalance, voltage harmonics and interharmonics, mains signalling on the supply voltage, rapid voltage changes, and current measurements. Emissions in the 2 kHz to 150 kHz range are considered in Annex C (informative), and over- and underdeviations are considered in Annex D (informative). Depending on the purpose of the measurement, all or a subset of the phenomena on this list may be measured. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the measurement method for current, previously informative, is now normative with some changes;
- the measurement method for RVC (rapid voltage change) has been added;
- the measurement method for conducted emissions in the 2 kHz to 150 kHz range has been added in informative Annex C;
- underdeviation and overdeviation parameters are moved to informative Annex D;
- Class A and Class S measurement methods are defined and clarified, while Class B is moved to informative Annex E and considered for future removal;
- measurement methods continue in this standard, but responsibility for influence quantities, performance, and test procedures are transferred to IEC 62586-2.
The contents of the corrigendum of December 2016 have been included in this copy.
This consolidated version consists of the third edition (2015) and its amendment 1 (2021). Therefore, no need to order amendment in addition to this publication.
