AS 61869.9:2021 pdf free.Instrument transformers Part 9: Digital interface for instrument transformers (IEC 61869-9:2016 (ED 1.0) MOD).
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 6 1850-9-2, 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.
