CSA序言这是CAN/CSA-C61000-3-6《电磁兼容性（EMC）-第3-6部分: 限值——畸变装置与中压、高压和超高压电力系统连接的排放限值评估，采用了标题相同的IEC（国际电工委员会）技术报告61000-3-6（第二版，2008-02），但存在加拿大偏差。它取代了 第一版于2004年出版，作为CAN/CSA-C61000-3-6，电磁兼容性（EMC）-第3部分:限值-第6节:中压和高压电力系统中畸变负载发射限值的评估（采用CEI/IEC 1000-3-6:1996）。1范围本技术报告本质上是信息性的，提供了原则指导，这些原则可作为确定扭曲装置与中压、高压和超高压公共电力系统连接要求的基础（低压装置在其他IEC文件中涵盖）。 在本报告中，畸变装置指产生谐波和/或间谐波的装置（可能是负载或发电机）。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，这将有助于为所有相关客户提供足够的服务质量。在解决安装问题时，本文件无意取代排放限值的设备标准。

CSA PrefaceThis is the second edition of CAN/CSA-C61000-3-6, Electromagnetic compatibility (EMC) - Part 3-6: Limits - Assessment of emission limits for the connection of distorting installations to MV, HV and EHV power systems, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Technical Report 61000-3-6 (second edition, 2008-02). It supersedes the first edition published in 2004 as CAN/CSA-C61000-3-6, Electromagnetic compatibility (EMC) - Part 3: Limits - Section 6: Assessment of emission limits for distorting loads in MV and HV power systems (adopted CEI/IEC 1000-3-6:1996).1 ScopeThis 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.
