CSA序言 这是CAN/CSA-C61000-3-7《电磁兼容性（EMC）-第3-7部分: 限值——对波动装置与中压、高压和超高压电力系统连接的排放限值的评估，这是在不修改同名IEC（国际电工委员会）技术报告61000-3-7（第二版，2008-02）的情况下采用的。它取代了2004年出版的第一版，即CAN/CSA-C61000-3-7，电磁兼容性（EMC）-第3部分:限值-第7节:中压和高压电力系统中波动负载发射限值的评估（采用CEI/IEC 1000）- 3-7:1996). 1范围 IEC 61000的本部分提供了原则指南，这些原则可作为确定波动装置与中压、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文件中有介绍）。在本报告中，波动装置指产生电压闪烁和/或快速电压变化的装置（可能是负载或发电机）。其主要目标是为系统运营商或所有者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 Preface This is the second edition of CAN/CSA-C61000-3-7, Electromagnetic compatibility (EMC) - Part 3-7: Limits - Assessment of emission limits for the connection of fluctuating installations to MV, HV and EHV power systems, which is an adoption without modification of the identically titled IEC (International Electrotechnical Commission) Technical Report 61000-3-7 (second edition, 2008-02). It supersedes the first edition published in 2004 as CAN/CSA-C61000-3-7, Electromagnetic compatibility (EMC) - Part 3: Limits - Section 7: Assessment of emission limits for fluctuating loads in MV and HV power systems (adopted CEI/IEC 1000-3-7:1996). 1 Scope This part of IEC 61000 provides guidance on principles which can be used as the basis for determining the requirements for the connection of fluctuating installations to MV, HV and EHV public power systems (LV installations are covered in other IEC documents). For the purposes of this report, a fluctuating installation means an installation (which may be a load or a generator) that produces voltage flicker and / or rapid voltage changes. 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.
