本技术报告本质上是信息性的，提供了原则指导，可用作确定失真装置与中压、高压和超高压公共电力系统连接要求的基础（低压装置包含在其他IEC文件中）。就本报告而言，失真装置是指产生谐波和/或间谐波的装置（可以是负载或发电机）。主要目标是为系统运营商或业主提供工程实践方面的指导，这将有助于为所有连接的客户提供足够的服务质量。在处理装置时，本文件无意取代排放限值的设备标准。该报告讨论了系统吸收扰动的能力的分配。它没有解决如何减轻干扰，也没有解决如何增加系统的容量。由于本报告中概述的指南必然基于某些简化假设，因此不能保证这种方法总是为所有谐波情况提供最佳解决方案。就工程而言，在全部或部分应用给定的评估程序时，应灵活和判断地使用推荐的方法。系统操作员或所有者负责规定将失真装置连接到系统的要求。畸变安装应理解为客户的完整安装（即包括畸变和非畸变部件）。与谐波有关的问题分为两个基本类别:/ -由转换器和谐波源注入供电系统的谐波电流，在系统中产生谐波电压。谐波电流和由此产生的电压都可以被认为是传导现象。 -对通信系统造成干扰的谐波电流。这种现象在高次谐波频率下更明显，因为电路之间的耦合增加，并且因为通信电路在可听范围内的更高灵敏度。 本报告为协调不同电压等级之间的谐波电压提供了指导，以满足使用点的兼容性水平。本报告中的建议没有解决通信电路中的谐波干扰现象（即。e.仅解决了上述类别中的第一个）。第二版取消并取代了1996年出版的第一版，构成了技术修订。这个版本比第一版明显更加精简，它反映了在第一版的应用中获得的经验。作为该精简过程的一部分，IEC/TR 61000-3-6的第二版没有解决通信电路干扰问题。关于这一点的第9条（第10条）被删除，因为这没有适当地解决电话干扰的排放限制。调整范围以指出IEC/TR 61000-3-6未解决通信电路干扰问题。该版本还与IEC/TR 61000-3-7和IEC/TR 61000-3-13保持一致。根据IEC指南107，本技术报告具有基本EMC出版物的地位。

This Technical Report, which is informative in its nature, provides guidance on principles which can be used as the basis for determining the requirements for the connection of distorting installations to MV, HV and EHV public power systems (LV installations are covered in other IEC documents). For the purposes of this report, a distorting installation means an installation (which may be a load or a generator) that produces harmonics and/or interharmonics. The primary objective is to provide guidance to system operators or owners on engineering practices, which will facilitate the provision of adequate service quality for all connected customers. In addressing installations, this document is not intended to replace equipment standards for emission limits. The report addresses the allocation of the capacity of the system to absorb disturbances. It does not address how to mitigate disturbances, nor does it address how the capacity of the system can be increased. Since the guidelines outlined in this report are necessarily based on certain simplifying assumptions, there is no guarantee that this approach will always provide the optimum solution for all harmonic situations. The recommended approach should be used with flexibility and judgment as far as engineering is concerned, when applying the given assessment procedures in full or in part. The system operator or owner is responsible for specifying requirements for the connection of distorting installations to the system. The distorting installation is to be understood as the customer's complete installation (i.e. including distorting and non-distorting parts). Problems related to harmonics fall into two basic categories:
/ - Harmonic currents that are injected into the supply system by converters and harmonic sources, giving rise to harmonic voltages in the system. Both harmonic currents and resulting voltages can be considered as conducted phenomena.
- Harmonic currents that induce interference into communication systems. This phenomenon is more pronounced at higher order harmonic frequencies because of increased coupling between the circuits and because of the higher sensitivity of the communication circuits in the audible range.
This report gives guidance for the co-ordination of the harmonic voltages between different voltage levels in order to meet the compatibility levels at the point of utilisation. The recommendations in this report do not address harmonic interference phenomena in communication circuits (i.e. only the first of the above categories is addressed). This second edition cancels and replaces the first edition published in 1996 and constitutes a technical revision. This edition is significantly more streamlined than first edition, and it reflects the experiences gained in the application of the first edition. As part of this streamlining process, this second edition of IEC/TR 61000-3-6 does not address communications circuit interference. Clause 9 on this (section 10) was removed, as this did not suitably address emission limits for telephone interference. The scope has been adjusted to point out that IEC/TR 61000-3-6 does not address communications circuit interference. This edition has also been harmonised with IEC/TR 61000-3-7 and IEC/TR 61000-3-13. This Technical Report has the status of a basic EMC publication in accordance with IEC Guide 107.
