CSA C61869-2:14 (R2019)

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.
