AS 61869.13:2021 pdf free download – lnstrument transformers Part 13: Stand-alone merging unit.
This part of IEC 61869 is a product standard and covers only additional requirements for standalone merging units (SAMU5) used for AC applications having rated frequencies from 15 Hz to 100 Hz. The digital output format specification is not covered by this document: it Is standardized In IEC 61869-9 as an application of IEC 61850. which specifies the power utility communication architecture.
This document covers SAMUS having standardized analogue inputs (for example: 1 A. 5 A, 3,25 V 1 ‘3 or 100 V I ,3) provided by instrument transformers compliant with relevant product standards (e.g. IEC 61869-2 to IEC 61869-5, IEC 61869-7, IEC 61869-8. IEC 61869-10. 1EC61869-11, IEC 60044-1 to 1EC60044-6, IEC 60185, IEC 60186, IEEE C57.13), and alms to convert them to the digital output compliant with IEC 61869-9. Other input and output types are outside the scope of this document. Appropriate SAMU functionality can be combined with swltchgear controller functionality defined in IEC 62271.3 or other lED functionality defined in IEC 60255 (all parts).
Cyber security requirements are outside the scope of this document and are covered by the IEC 62351 series.
