[中文适用范围]： IEC 61000-4 的这一部分涉及电气和电子设备在运行条件下的抗扰度要求和测试方法，涉及： a) 主要出现在安装在高压和介质中的电源、控制和信号电缆中的重复阻尼振荡波电压（HV/MV）变电站； b) 重复阻尼振荡波主要出现在安装在气体绝缘变电站（GIS）中的电力、控制和信号电缆中，在某些情况下也出现在空气绝缘变电站（AIS）中或由于 HEMP 现象而安装在任何装置中。本标准的目的是定义： – 测试电压和电流波形； – 测试级别范围； - 测验设备; – 测试设置； - 测试程序。 [外文原描述]： This part of IEC 61000-4 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, with regard to: a) repetitive damped oscillatory waves occurring mainly in power, control and signal cables installed in high voltage and medium voltage (HV/MV) substations; b) repetitive damped oscillatory waves occurring mainly in power, control and signal cables installed in gas insulated substations (GIS) and in some cases also air insulated substations (AIS) or in any installation due to HEMP phenomena. The object of this basic standard is to establish the immunity requirements and a common reference for evaluating in a laboratory the performance of electrical and electronic equipment intended for residential, commercial and industrial applications, as well as of equipment intended for power stations and substations, as applicable. The purpose of this standard is to define: - test voltage and current waveforms; - ranges of test levels; - test equipment; - test setup; - test procedure. The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to damped oscillatory waves. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. It has the status of a basic EMC publication in accordance with IEC Guide 107.
