About This Item
PC57.12.38/D6.4, Mar, 2009 is an inactive technical standard for cooled, single phase distribution transformers with high voltage ratings up to 34 500 GrdY/19 920 volts and low voltage 240/120 volts, covering units 167 kVA and smaller. It is relevant to power, energy, and industry applications where transformer design, ratings, and performance need a clear reference. For procurement, engineering, and compliance review, this standard helps define expectations for equipment used in distribution systems.
What is PC57.12.38/D6.4, Mar, 2009?
This specification addresses the technical requirements for a particular class of cooled, single phase distribution transformers. PC57.12.38/D6.4, Mar, 2009 focuses on equipment intended for moderate-voltage service on the primary side and 240/120 volts on the secondary side, with ratings at 167 kVA and below. In practical terms, it provides a structured basis for design, testing, and rating decisions so that transformers in this category can be evaluated consistently.
Where is PC57.12.38/D6.4, Mar, 2009 used?
This standard is most applicable in utility distribution and related power infrastructure where single phase transformers step voltage down for end-use supply. It may be used in feeder and service applications, equipment specification, and acceptance testing for transformers serving residential or light commercial loads. Because PC57.12.38/D6.4, Mar, 2009 defines a narrow technical scope, it is especially useful when selecting or comparing transformers that must match a specific cooling method, voltage class, and kVA range.
Why is PC57.12.38/D6.4, Mar, 2009 important?
PC57.12.38/D6.4, Mar, 2009 matters because transformer performance and interchangeability depend on clear technical requirements. Using a defined standard supports consistent design choices, safer procurement, and more reliable acceptance checks for distribution equipment. It also helps reduce misalignment between purchaser expectations and supplier offerings, especially when voltage ratings, cooling method, and capacity limits must be controlled. For organizations working with legacy or archived specifications, this document can remain a useful reference point.
