IEC 61378-1:2011/COR1:2012

IEC 61378-1:2011/COR1:2012 is a corrigendum tied to Converter transformers - Part 1: Transformers for industrial applications, providing a formal correction to the parent document IEC 61378-1:2011. For engineering, procurement, and compliance teams, it matters because even a small published correction can affect how the technical document is interpreted during specification review, conformity assessment, and documentation control. As a supporting reference, it helps organizations keep electrical equipment records and technical validation aligned with the corrected edition.

Overview of IEC 61378-1:2011/COR1:2012

This corrigendum functions as a modifying reference rather than a standalone technical specification. In practical terms, IEC 61378-1:2011/COR1:2012 is used to identify and apply corrections associated with converter transformers intended for industrial applications. It supports technical review of the parent part of the series by clarifying the published text where needed, helping teams maintain accuracy in engineering documentation, procurement specifications, and compliance workflows. For organizations working with transformer-related conformity assessment, it provides a controlled basis for documented evaluation.

Compliance applications of IEC 61378-1:2011/COR1:2012

Organizations may use IEC 61378-1:2011/COR1:2012 when reviewing transformer specifications, verifying project documents, or checking test and acceptance criteria against the corrected parent reference. It is relevant in workflows where converter transformers are selected, documented, or assessed for industrial electrical systems. The corrigendum can also support laboratory evaluation, quality workflows, and technical assessment activities by ensuring the underlying reference set is current. In procurement and regulatory preparation, it helps reduce ambiguity when confirming which published wording should guide the engineering specification.

Importance of compliance with IEC 61378-1:2011/COR1:2012

Using the corrected reference supports safety, interoperability, and testing consistency by reducing the risk of relying on superseded wording in the parent document. For teams responsible for engineering validation or conformity assessment preparation, IEC 61378-1:2011/COR1:2012 helps preserve traceability in technical documentation and quality assurance records. It is especially useful where procurement decisions, acceptance checks, or design reviews depend on an exact interpretation of transformer requirements. Maintaining the corrigendum alongside the parent text can improve operational consistency and lower compliance risk.
