: Sets standards for "normal" and "special" environmental factors, including ambient temperature, altitude, vibration, and pollution levels.
: 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
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:
: Establishes permissible limits for ratio and phase angle errors for both analogue and digital outputs.
: Covers rated frequencies from 15 Hz to 400 Hz , as well as dedicated DC applications.
