The IEC 61869 series replaced the older IEC 60044 standards to streamline specifications and accommodate digital technologies like merging units and non-conventional instrument transformers (NCITs). The series uses a modular two-part structure:

For engineers working with protection, metering, or substation automation, IEC 61869 is essential reading. It ensures instrument transformers meet modern grid requirements — from traditional analog outputs to digital interfaces in smart substations.

: It applies to both analogue and digital secondary signals.
