前言:这是CAN/CSA-C61869-2《互感器-第2部分:电流互感器的附加要求》的第一版，采用了标题相同的IEC（国际电工委员会）标准61869-2:2012（第1.0:2012版），但有加拿大的偏差。它与CAN/CSA-C61869-1一起取代了2007年出版的CAN/CSA-C60044-1《互感器第1部分:电流互感器》。为简洁起见，本标准通篇称为“CAN/CSA-C61869-2”。本标准是C61869系列互感器标准的一部分，该系列标准包括采用与IEC 61869系列标准有加拿大偏差的标准。 IEC 61869系列对之前的IEC 60044系列标准进行了重组和更新。CAN/CSA-C61869-1中列出了各种互感器类型的通用要求；该系列的其余标准规定了特定类型仪表变压器的要求。本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。CSA集团已将其作为加拿大国家标准发布。范围:IEC 61869的本部分适用于与额定频率为15 Hz至100 Hz的电气测量仪器和/或电气保护装置一起使用的新型感应电流互感器。

Preface:This is the first edition of CAN/CSA-C61869-2,Instrument transformers - Part 2: Additional requirements for current transformers, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 61869-2:2012 (edition 1.0:2012). Together with CAN/CSA-C61869-1, it supersedes CAN/CSA-C60044-1,Instrument transformers - Part 1: Current transformers, which was published in 2007.For brevity, this Standard will be referred to as "CAN/CSA-C61869-2" throughout.This Standard is part of the C61869 series of standards on instrument transformers, which consists of adoptions with Canadian deviations of the IEC 61869 series of standards. The IEC 61869 series restructures and updates the previous IEC 60044 series of standards. Requirements common to a variety of instrument transformer types are grouped in CAN/CSA-C61869-1; the remaining standards in the series state requirements for specific types of instrument transformers.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 61869 is applicable to newly manufactured inductive current transformers for use with electrical measuring instruments and/or electrical protective devices having rated frequencies from 15 Hz to 100 Hz.
