IEEE P57.12.10-2010/Cor2/D1, Jun 2013

P57.12.10-2010/Cor2/D1, Jun 2013 is a corrective technical document for the P57.12.10 standard, focused on Corregendum 2 changes to A.3.2.13 covering autotransformer LTC application considerations. In the power, energy, and industry applications context, it helps clarify how load tap changer application guidance should be interpreted for autotransformer designs. For engineers, reviewers, and procurement teams, this matters because even a targeted correction can affect design decisions, specification consistency, and compliant use of the base standard.

About P57.12.10-2010/Cor2/D1, Jun 2013

This document serves as a correction to a specific clause in P57.12.10-2010, refining the guidance in A.3.2.13 for autotransformer LTC application considerations. Such corrigenda are typically used to remove ambiguity, align technical wording, or correct an engineering detail that affects interpretation. For users working with transformer application requirements, P57.12.10-2010/Cor2/D1, Jun 2013 provides a narrow but important update that supports accurate reading of the underlying standard and reduces the risk of applying outdated guidance.

Where is P57.12.10-2010/Cor2/D1, Jun 2013 used?

This correction is most relevant in transformer specification, utility engineering, and equipment review workflows where autotransformer LTC behavior must be understood clearly. It may be consulted during design checks, technical submittals, maintenance planning, or procurement of power equipment for grid and industrial applications. Because the subject is tied to power, energy, and industry applications, the document is especially useful where voltage regulation, tap-changing performance, and transformer application notes must be evaluated against the standard’s corrected language.

Importance in practice

In practice, a corrigendum like P57.12.10-2010/Cor2/D1, Jun 2013 helps keep engineering decisions aligned with the intended technical requirements. Correct wording in autotransformer LTC application guidance can influence compliance reviews, equipment selection, and design consistency across projects. It may also help reduce misinterpretation during testing or specification writing, especially when teams rely on the standard to define acceptable application conditions. For organizations managing transformer-related documentation, the correction supports better control of technical risk.
