CAN/CSA-C61000-3-7:09 (R2022)

Description

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, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Technical Report 61000-3-7 (second edition, 2008-02). It supersedes the previous edition, published in 2004 as CAN/CSA-C61000-3-7 (adopted IEC 1000-3-7:1996), Electromagnetic compatibility (EMC) — Part 3: Limits — Section 7: Assessment of emission limits for fluctuating loads in MV and HV power systems. For brevity, this Standard will be referred to as “CAN/CSA-C61000-3-7” throughout. The primary objective of this adopted Technical Report is to provide guidance for engineering practices. It is intended to be informative and should not be considered normative. This Technical Report was reviewed for Canadian adoption by the CSA Subcommittee on Low-Frequency Electromagnetic Compatibility, under the jurisdiction of the CSA Technical Committee on Electromagnetic Compatibility and the CSA Strategic Steering Committee on Power Engineering and Electromagnetic Compatibility, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 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.
