The IEC 61869 series has modernized the way instrument transformers are specified, tested, and integrated into today's power grids — from conventional AC systems to digital substations, HVDC links, and renewable energy plants. The transition from IEC 60044 to IEC 61869 is now largely complete, making the series an essential reference for electrical engineers, utilities, manufacturers, and testing laboratories worldwide.
The 2023 edition is a major update, merging the previous IEC 61869-1:2007 (General Requirements) and IEC 61869-6:2016 (Low-power Instrument Transformers) into one unified document. iec 618691 pdf
IEC 61869-1 is the modern replacement for (CTs) and IEC 60044-2 (VTs). The IEC 61869 series has modernized the way
Specific test procedures for or insulation . The exact changes between the 2007 and 2023 versions . IEC 61869-1 is the modern replacement for (CTs)
Covers the general principles of error limits (ratio error and phase displacement) for both analog and digital secondary outputs. 5. Type and Routine Tests
IEC 61869-1 is the cornerstone standard for instrument transformer technology. By establishing a unified vocabulary and rigorous testing protocols, it ensures that the devices used to meter electricity and protect the grid are safe, reliable, and accurate, regardless of the manufacturer.
The document provides the necessary formulas and testing methods to verify the accuracy of current and voltage measurement in protective relay systems. Structure of the IEC 61869 Series
