: Covers both traditional analogue and modern digital secondary signals.
IEC 61869-1, titled "Instrument transformers – Part 1: General requirements," is a foundational "product family" standard. It defines the universal performance criteria, environmental conditions, and testing procedures that apply to all types of instrument transformers, including current (CTs) and voltage transformers (VTs).
Temperature limits, altitude adjustments, and vibration constraints for indoor and outdoor installations.
