本技术报告描述了电压骤降和短时中断的电磁干扰现象，包括其来源、影响、补救措施、测量方法和测量结果（只要可用）。 它们主要作为在公共供电系统网络上观察到的现象进行讨论，并对从这些系统接收能量供应的电气设备产生影响。

This technical report describes the electromagnetic disturbance phenomena of voltage dips and short interruptions in terms of their sources, effects, remedial measures, methods of measurement, and measurement results (in so far as these are available). They are discussed primarily as phenomena observed on the networks of public electricity supply systems and having an effect on electrical equipment receiving its energy supply from those systems.
