About This Item
PC57.12.38/D1.0, Febr 2016 is a corrigendum for phase distribution transformers rated 250 kVA and smaller, covering high voltage up to 34 500 GrdY/19 920 V and low voltage up to 480/240 V. It corrects an omission in the label of Figure 1, making the technical reference more accurate for engineers, manufacturers, and reviewers working with transformer design, labeling, and documentation in power and energy applications.
Overview of PC57.12.38/D1.0, Febr 2016
This technical document addresses a specific correction to the phase distribution transformer standard PC57.12.38. Its focus is narrow but important: clarifying a figure label tied to transformers used in distribution networks and related equipment specifications. For organizations that rely on the standard for design, compliance review, or purchasing decisions, PC57.12.38/D1.0, Febr 2016 helps ensure the referenced figure is interpreted correctly and supports consistent application of the transformer requirements.
Typical use cases
PC57.12.38/D1.0, Febr 2016 is typically used when reviewing distribution transformer drawings, verifying nameplate or figure references, or checking technical documentation for small phase transformers in utility and industrial power systems. It is relevant to equipment rated within the stated high-voltage and low-voltage limits, especially where precise labeling affects interpretation of design details, procurement records, or compliance checks. The corrigendum is useful during specification review and document control workflows.
Why it matters
Even a small omission in a figure label can create confusion during engineering review, factory testing, or specification comparison. PC57.12.38/D1.0, Febr 2016 helps reduce that risk by correcting the record for the affected transformer standard. In practice, this supports clearer compliance interpretation, more reliable procurement alignment, and fewer errors when tracing requirements across design, testing, and documentation. For standards management, accurate references are essential to consistency.
