Preface:

This is the first edition of CSA C61869-9, Instrument transformers — Part 9: Digital interface for instrument transformers, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 61869-9 (first edition, 2016-04). It replaces relevant parts of CAN/CSA-C60044-8:07 (adopted IEC 60044-8:2002), Instrument transformers — Part 8: Electronic current transformers. It is part of the CSA C61869 series of Standards on instrument transformers, which consists of adoptions with Canadian deviations of the IEC 61869 series of Standards.

This Standard is intended to be used in conjunction with CAN/CSA-C61869-1:14, Instrument transformers — Part 1: General requirements (adopted IEC 61869-1:2007, with Canadian deviations); and CSA C61869-6:20, Instrument transformers — Part 6: Additional general requirements for low-power instrument transformers (adopted IEC 61869-6:2016, with Canadian deviations).

Requirements common to all instrument transformer types are grouped in CAN/CSA-C61869-1. Requirements specific to conventional instrument transformer types are grouped in CAN/CSA-C61869-2, CAN/CSA-C61869-3, CAN/CSA-C61869-4, and CAN/CSA-C61869-5. Those CSA Group Standards present many inherited Canadian deviations justified by the specific conditions, practices, and regulations in Canada.

Requirements common to low-power instrument transformers (LPIT) used for ac applications having rated frequencies from 15 Hz to 100 Hz covering MV, HV, and EHV or used for dc applications are grouped in CSA C61869-6.

The remaining Standards in the series state requirements for specific types of instrument transformers.

The LPIT has low-power analog output or digital output. The requirements for the digital interface associated with LPIT are grouped in CSA C61869-9.

Canada has actively participated in the development of IEC 61869-9, in order to enforce specific Canadian conditions. It should be noted that Parts 6 to 13 of the IEC 61869 series specify the requirements for ac LPIT as well as the interfaces necessary to implement the LPIT into an integrated system for protection and measurement. Such a system uses a universal digital transmission protocol compatible with IEC 61850, and has a digital output. In order to ensure full interoperability, Canadian deviations in CSA C61869-9 are minimal.

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 a product family standard applicable to instrument transformers with digital output. The product standard is composed of IEC 61869-1 and IEC 61869-6, in addition to this standard and the relevant product specific standards in the IEC 61869 series (Part 7, Part 8, Part 12, Part 13, Part 14, and Part 15).

This standard defines requirements for digital communications of instrument transformer measurements. It is based on the IEC 61850 series, UCA international users group document Implementation guideline for digital interface to instrument transformers using IEC 61850-9-2, and the relevant parts of IEC 60044-8 that are replaced by this standard. It includes additional improvements including the IEC 61588 network based time synchronization.10C.
