[中文适用范围]： IEC 61000-4 的这一部分定义了基频为 50 Hz 或 60 Hz 的交流电源系统中电能质量参数结果的测量和解释方法。每个相关参数的测量方法都以给出可靠且可重复的结果@的方式进行描述，无论方法的实现如何。本标准规定了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。本标准考虑的电能质量参数包括：电源频率@电源电压幅值@闪变@电源电压骤降和骤升@电压中断@瞬态电压@电源电压不平衡@电压谐波和间谐波@电源电压上的干线信号@快速电压更改@和当前测量值。附件 C（资料性）@ 考虑了 2 kHz 至 150 kHz 范围内的发射，附件 D（资料性）考虑了过偏差和欠偏差。根据测量的目的@可以测量此列表中的所有现象或现象的子集。注 1：验证是否符合本标准的测试方法可在 IEC 62586-2 中找到。注 2：本标准承认插入电力系统和仪器之间的传感器的影响，但未详细说明。有关传感器影响的指南可参见 IEC TR 61869-103。 [外文原描述]： IEC 61000-4-30:201 5 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.
