IEEE P57.12.10_Cor2/D2, August 2013

P57.12.10_Cor2/D2, August 2013 is a corrigendum addressing correction of A.3.2.13 on autotransformer LTC application considerations. It is relevant to power engineering work where load tap changer behavior, transformer application, and related dielectric and circuit considerations must be interpreted correctly. For teams working with equipment specification, review, or compliance, this document helps ensure the technical guidance is read as intended and applied consistently in design and procurement decisions.

P57.12.10_Cor2/D2, August 2013 overview

This standard document serves as a targeted correction to the underlying technical guidance for autotransformer LTC application considerations. In practice, P57.12.10_Cor2/D2, August 2013 is useful when a specification, engineering review, or test interpretation depends on the corrected wording in A.3.2.13. Its context sits within power, energy, and industrial applications, with emphasis on transformer-related components, circuits, and material behavior that can affect performance, insulation coordination, and operating limits.

Typical use cases

This corrigendum is typically consulted during transformer application studies, especially where autotransformer load tap changer arrangements are being reviewed for utility or industrial power systems. It may also support engineering documentation, bid evaluation, and technical audits when accurate interpretation of the corrected clause is important. Designers, specifiers, and maintenance engineers can use P57.12.10_Cor2/D2, August 2013 to align equipment selection and application notes with the corrected guidance for LTC-related operating considerations.

Why this standard matters

Accuracy in corrected technical requirements matters because small wording changes can affect how equipment is applied, tested, and accepted. P57.12.10_Cor2/D2, August 2013 helps reduce the risk of misinterpretation in autotransformer LTC planning, particularly where system performance, insulation stress, or operating compatibility must be considered carefully. Using the corrigendum supports clearer compliance checks, more consistent engineering decisions, and better alignment between design intent and procurement or review requirements.
