As a revised edition released in 2023, IEC 61869-1:2023 supersedes the 2007 version of the same standard as well as IEC 61869-6:2016, updating technical content to meet the latest industry needs of electrical equipment. It should be noted that this standard does not apply to low-voltage instrument transformers (≤1 kV AC or ≤1.5 kV DC), which are instead regulated by IEC 61869-201. Serving as a foundational guideline, it provides uniform technical specifications for the design, production, testing and quality evaluation of instrument transformers, ensuring their compatibility and reliability in electrical systems.
