The IEC 61869-1 standard is the "General Requirements" foundational document for the IEC 61869 series, which governs (such as current and voltage transformers) used in electrical power systems. Key Overview of IEC 61869-1 Mechanical and Safety: Includes standards for internal arc
Outlines requirements for ambient temperature, altitude, vibration, and corrosion resistance. Mechanical and Safety: Includes standards for internal arc fault protection
, establishing the general requirements for newly manufactured devices used in electrical measuring and protective systems. As a "product family" standard, it serves as the base document that must be used alongside specific part standards (like Part 2 for current transformers or Part 3 for voltage transformers) to form a complete product specification. iTeh Standards Scope and Applicability The most recent edition, IEC 61869-1:2023
