IEC 61000的这一部分是一份技术报告，提供了背景材料，描述了制定IEC标准的动机，这些标准涉及高功率电磁场（HPEM）场、电流和电压对民用系统的影响。鉴于新兴的瞬态天线技术和数字电子技术的日益使用，设备被这些环境扰乱或损坏的可能性令人担忧。本文件首先对该主题进行了一般性介绍，并列出了所使用的相关定义。在这些条款之后，描述了令人关注的HPEM环境，并讨论了这些环境在民事系统中可能产生的各种影响。最后，总结了用于保护系统免受这些环境影响的技术。更多详细信息将在本61000系列的单独文件中提供。

This part of IEC 61000 is a technical report that provides background material describing the motivation for developing IEC standards on the effects of high power electromagnetic (HPEM) fields, currents and voltages on civil systems. In the light of newly emerging transient antenna technology and the increasing use of digital electronics, the possibility of equipment being upset or damaged by these environments is of concern. This document begins with a general introduction to this subject and a listing of the pertinent definitions used. Following these clauses, the HPEM environments that are of concern are described and a discussion of the various effects that these environments can induce in civil systems is presented. Finally, techniques used to protect systems against these environments are summarised. More detailed information will be provided in separate documents in this 61000 series.
