It addresses special conditions like pollution, temperature, and altitude.
Temperature-rise test, Impulse voltage tests, Electromagnetic Compatibility (EMC) tests.
It applies to newly manufactured instrument transformers with either analogue or digital outputs for systems with nominal voltages above Technical Consolidation: The latest 2023 edition (IEC 61869-1:2023) merged with IEC 61869-6:2016 iec 618691 pdf
The standard IEC 61869-1 serves as the foundational "Product Family" document for all instrument transformers. It establishes general requirements that must be met by every type of transformer—such as current, voltage, or combined units—before specific requirements from other parts of the IEC 61869 series are applied. iTeh Standards 📄 Standard Overview Official Title : Instrument Transformers – Part 1: General Requirements. Latest Edition
Before engineering an instrument transformer, manufacturers must adhere to the standard ratings defined in Part 1: It establishes general requirements that must be met
