The is an indispensable resource for anyone working with instrument transformers in modern power systems. As the foundational document of the IEC 61869 series, it establishes the universal requirements that all instrument transformers must meet—covering everything from ratings and design to testing and digital interfaces.
For electrical engineers, substation designers, and testing professionals, obtaining and understanding the is an essential task. As the foundational product family standard, it sets the universal requirements that all instrument transformers must meet, bridging the gap between conventional analog and modern digital technologies.

It provides rules for insulation, mechanical strength, and the design of terminal markings to ensure safety and operational reliability. 4. Testing Procedures
It defines maximum permissible temperature rises for windings and insulating materials to prevent premature aging or thermal runaway.
A notable feature of the latest edition is its coordination with digital substation standards. Characteristics of the are standardized in IEC 61869-9 , which applies the IEC 61850 horizontal standard series covering communication networks and systems for power utility automation. This integration reflects the industry's shift toward digital substations and process bus architectures. As the foundational product family standard, it sets
The most recent version, IEC 61869-1:2023 (Edition 2.0), was published on 14 June 2023. This edition cancels and replaces the first edition (published in 2007) and IEC 61869-6:2016.
Many national standards bodies, such as ANSI or DIN, offer the document in PDF format.
As the global electrical grid continues its transformation toward renewable energy integration, digital substations, and increased power quality requirements, the importance of this foundational standard will only grow. Whether you are designing new transformers, specifying equipment for a substation upgrade, or verifying compliance with international requirements, the IEC 61869-1 PDF is an indispensable reference that belongs in every power engineering professional's technical library.
Before this standard was introduced, current transformers (CTs) and voltage transformers (VTs) were governed by separate, older standards (like IEC 60044-1 and IEC 60044-2). The IEC 61869 series unified these documents into a single, cohesive framework. Part 1 serves as the baseline document. All subsequent parts in the series (such as Part 2 for CTs or Part 3 for VTs) build directly upon the rules established in Part 1. Structure of the IEC 61869 Series
Older standards treated instrument transformers purely as analog, copper-wound copper devices. IEC 61869-1 explicitly paves the way for modern smart grids by establishing definitions that accommodate and optical sensors.
