IEC 61869-4:2013/COR1:2014

IEC 61869-4:2013/COR1:2014 is a corrigendum linked to the combined transformers requirements in IEC 61869-4:2013, and it is relevant when teams need to work from the corrected technical text rather than the base publication alone. Corrigenda matter in engineering and compliance workflows because even small editorial or technical corrections can affect interpretation, verification activities, and documented evaluation. For organizations handling instrument transformers, this reference helps support more reliable technical review, procurement checks, and conformity assessment preparation.

Purpose of IEC 61869-4:2013/COR1:2014

The purpose of IEC 61869-4:2013/COR1:2014 is to provide the official correction to the document covering additional requirements for combined transformers. As a supporting reference to IEC 61869-4:2013, it helps users align engineering documentation and testing workflows with the corrected wording of the source material. In practical terms, it can be important for technical validation, specification review, and regulatory preparation where accuracy of the normative text affects interpretation, product evaluation, or certification planning.

Compliance applications of IEC 61869-4:2013/COR1:2014

This corrigendum is typically used by utilities, manufacturers, laboratories, and procurement teams that rely on instrument transformer documentation for verification and conformity assessment. It is especially relevant where combined transformers are part of electrical equipment assessments, acceptance testing, or design review packages. During compliance workflows, the corrected text may be consulted to ensure that test programs, engineering specifications, and quality workflows reflect the intended requirements of the parent document. It can also support controlled document management and technical assessment activities.

Benefits of IEC 61869-4:2013/COR1:2014

Using IEC 61869-4:2013/COR1:2014 helps reduce risk by ensuring teams reference the corrected requirements when evaluating combined transformers. That supports safer engineering decisions, more consistent testing outcomes, and stronger interoperability between internal specifications and external compliance references. For procurement and laboratory evaluation, the corrigendum can improve confidence that product review and conformity assessment are based on the most accurate published wording. It also helps maintain operational consistency across documentation, validation, and approval processes.
