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.
