The transition to the IEC 61869 series represents a shift toward more integrated power system standards. By adhering to Part 1, manufacturers and utilities ensure that instrument transformers are compatible with modern digital substations while maintaining the safety and precision required for high-voltage infrastructure.

: Applies to instrument transformers with analogue or digital outputs used for measurement, protection, and control. Iec 61869-1 Pdf

Its primary function is to serve as the "umbrella" document for the entire IEC 61869 series. While subsequent parts of the series deal with specific technologies (like inductive CTs, capacitor VTs, or electronic transformers), Part 1 establishes the baseline definitions, general requirements, and test methodologies that apply to all instrument transformers. The transition to the IEC 61869 series represents

Establishes the framework for how error limits (current and phase displacement) are defined, though specific values like 0.1, 0.2, or 0.5 are typically detailed in part 2. www.ijareeie.com 4. Testing and Verification Its primary function is to serve as the
