- IEC 61869-1 is the general part of the IEC 61869 series covering instrument transformers (ITs), setting common requirements, definitions, and tests that apply across the series (e.g., voltage transformers, current transformers, capacitive voltage transformers).
- Practical use: it defines performance classes, safety and insulation requirements, accuracy testing, environmental and mechanical tests, and documentation/marking obligations that manufacturers, test labs, utilities, and consultants rely on.
