IEC TS 61850-1-2:2020/AMD1:2022

IEC TS 61850-1-2:2020/AMD1:2022 provides Amendment 1 to Communication networks and systems for power utility automation - Part 1-2: Guideline on extending IEC 61850, supporting technical review and controlled implementation work around the parent document. It is relevant where teams need a compliance reference for extending IEC 61850-based communication and automation systems while maintaining operational consistency, documented evaluation, and interoperability expectations. For engineering, testing, and procurement workflows, it helps define how updates to the guidance should be interpreted alongside the original technical document.

Purpose of IEC TS 61850-1-2:2020/AMD1:2022

The purpose of IEC TS 61850-1-2:2020/AMD1:2022 is to modify and refine the guidance in the parent technical specification on extending IEC 61850 for power utility automation. As an amendment, it is typically used to keep engineering documentation aligned with the latest published direction, especially where technical assessment, conformity assessment preparation, or internal quality workflows depend on accurate interpretation of the guideline. It supports organizations that need a stable basis for evaluating system extensions and maintaining consistent documentation practices.

Compliance applications of IEC TS 61850-1-2:2020/AMD1:2022

In compliance workflows, this amendment is generally consulted together with IEC TS 61850-1-2:2020 when reviewing networked automation systems, utility communication architectures, and related implementation documentation. It may be used by engineering teams, test laboratories, and procurement specialists during technical validation, vendor comparison, and regulatory preparation for power utility projects. Because it is a supporting document linked to the parent reference, it is most useful when a project requires accurate adoption of the updated guidance for extending IEC 61850 in practical design and verification activities.

Benefits of IEC TS 61850-1-2:2020/AMD1:2022

Using IEC TS 61850-1-2:2020/AMD1:2022 alongside the parent document can improve technical consistency across design, review, and testing stages. It supports safer implementation decisions by helping teams rely on the most current published guidance, which is important for interoperability, risk reduction, and conformity assessment preparation. For organizations managing electrical equipment or automation projects, the amendment can also help streamline documentation control, reduce ambiguity in procurement reviews, and strengthen verification activities before deployment or acceptance.

• Amendment linked to the parent guidance on extending IEC 61850-based power utility automation systems
• Useful for technical review, documented evaluation, and engineering documentation control
• Supports conformity assessment preparation and verification activities in utility automation workflows
• Relevant to interoperability-focused projects where updated guidance must be applied consistently
