: Covers rated frequencies from 15 Hz to 400 Hz , as well as dedicated DC applications.
: General requirements for low-voltage (LV) systems ( ≤is less than or equal to 1 kV AC or ≤is less than or equal to 1.5 kV DC) are handled separately by IEC 61869-201 . Key Technical Requirements iec 618691 pdf
The standard, titled "Instrument Transformers – Part 1: General Requirements," serves as the foundational "product-family" document for the entire IEC 61869 series. It establishes the core technical and safety specifications that apply to all types of newly manufactured instrument transformers, ensuring they provide accurate signals for measurement, protection, and control in high-voltage (HV) electrical systems. Scope and Applicability : Covers rated frequencies from 15 Hz to
As a general framework, IEC 61869-1 must be read alongside specific product standards (like Part 2 for Current Transformers or Part 3 for Inductive Voltage Transformers). It defines: It establishes the core technical and safety specifications
: Defines rated primary and secondary insulation levels to ensure reliability against electrical hazards.
: Sets standards for "normal" and "special" environmental factors, including ambient temperature, altitude, vibration, and pollution levels.
: Covers rated frequencies from 15 Hz to 400 Hz , as well as dedicated DC applications.
