Accuracy requirements – General principles for accuracy classes and limits of errors (detailed in respective part standards).

Nameplate markings – Mandatory and optional information.

The “-1” in the title signifies that this document is always used in conjunction with a product-specific part. For example:

You cannot certify a transformer based on Part 1 alone; you must also meet the relevant product-specific part. The “-1” in the title signifies that this

IEC 61869-1 is the foundational standard for all instrument transformers (voltage, current, and combined types). It specifies general rules and requirements that are supplemented by other parts of the IEC 61869 series (e.g., 61869-2 for current transformers, 61869-3 for inductive voltage transformers, 61869-5 for capacitive voltage transformers, etc.). 61869-2 for current transformers

Understanding IEC 61869-1 requires a brief look at history. For decades, the industry relied on the IEC 60044 series of standards. However, as technology evolved—specifically with the introduction of electronic (digital) instrument transformers—the old standards became inadequate.

The IEC 60044 series was replaced by the IEC 61869 series to create a more modular and modern framework. IEC 61869-1 consolidated the general requirements previously scattered across several older documents, creating a unified starting point for both traditional inductive transformers and modern low-power electronic transformers.
