IEC 61869-5:2011/COR1:2015

IEC 61869-5:2011/COR1:2015 is a corrigendum to the document for instrument transformers, specifically the part covering additional requirements for capacitor voltage transformers. It matters for engineering and compliance teams because corrigenda are used to correct or refine the parent technical reference, helping ensure that design reviews, test plans, and procurement specifications are aligned with the intended requirements of IEC 61869-5:2011/COR1:2015 and its parent document. For organizations working with voltage measurement equipment, it supports more accurate technical document control.

Overview of IEC 61869-5:2011/COR1:2015

IEC 61869-5:2011/COR1:2015 functions as a supporting correction document connected to IEC 61869-5:2011. Based on the title, it relates to additional requirements for capacitor voltage transformers, which are used in electrical measurement and protection applications. In practice, a corrigendum is relevant when teams need to confirm that the published requirements used for technical assessment, conformity assessment, and laboratory evaluation reflect the corrected wording. It is typically consulted alongside the parent reference during documented evaluation and engineering validation.

Compliance applications of IEC 61869-5:2011/COR1:2015

This corrigendum is commonly relevant during specification review, supplier qualification, and test documentation for capacitor voltage transformers used in power system environments. It may be used by manufacturers, testing laboratories, utilities, and procurement teams when verifying that product documentation and verification activities are based on the corrected requirements in IEC 61869-5:2011/COR1:2015. It can also support regulatory preparation and quality workflows where accurate referencing of the parent standard is important for operational consistency and technical compliance.

Importance of compliance with IEC 61869-5:2011/COR1:2015

Using the corrected reference helps reduce the risk of relying on outdated or ambiguous wording during engineering and testing workflows. For capacitor voltage transformers, accurate requirements are important for safety, performance validation, and interoperability within electrical equipment and protection systems. Compliance teams often depend on corrigenda to maintain consistency across technical specifications, test reports, and procurement records. That makes IEC 61869-5:2011/COR1:2015 useful for risk management, conformity assessment preparation, and quality assurance activities tied to the parent document.
