标准摘要
[中文适用范围]： IEC 61000-4 的这一部分定义了 50/60 Hz 交流电源系统中电能质量参数结果的测量和解释方法。针对每种相关类型的参数描述了测量方法，无论使用何种兼容仪器及其环境条件，都可以获得可靠、可重复和可比较的结果。本标准规定了原位测量的测量方法。本标准涵盖的参数测量仅限于可在电力系统中进行的那些现象。这些包括适当的电压和/或电流参数。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、电压和电流谐波和间谐波、电源电压和电源信号电压快速变化。根据测量的目的，可以测量该列表中的全部或部分现象。本标准是性能规范，而不是设计规范。本标准中影响量范围内的不确定度测试确定了性能要求。该标准给出了测量方法，但没有设定阈值。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。阐述了在带电电路上安装监视器的注意事项。 [外文原描述]： Defines the methods for measurement and interpretation of results for power quality parameters in 50/60 Hz a.c. power supply 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 and current harmonics and interharmonics, mains signalling on the supply voltage and rapid voltage changes. Depending on the purpose of the measurement, all or a subset of the phenomena on this list may be measured. This standard is a performance specification, not a design specification. The uncertainty tests in the ranges of influence quantities in this standard determine the performance requirements. This standard gives measurement methods but does not set thresholds. The contents of the corrigendum of August 2006 have been included in this copy.
