About This Item
C57.12.23-1992 is a technical standard for voltage connectors used in power equipment, covering high-voltage applications up to 24 940 GrdY/14 400 V and low-voltage systems at 240/120 V for units 167 kVA and smaller. It is relevant to power, energy, and industry applications where connector design must support dependable electrical interfaces, appropriate insulation, and consistent performance. For procurement, engineering, and compliance review, C57.12.23-1992 helps define the connector requirements that affect safe equipment integration.
What is C57.12.23-1992?
This standard sets out requirements for voltage connectors intended for transformer and related power equipment, with separate attention to high-voltage and low-voltage service conditions. C57.12.23-1992 is used to guide connector construction, ratings, and compatibility so that electrical connections can be specified and evaluated consistently. In practice, it supports the selection of connectors that suit the voltage class, equipment size, and installation environment. The document is especially useful when comparing designs or checking technical compliance for power-system components.
Where is C57.12.23-1992 used?
C57.12.23-1992 is typically applied in the design and specification of connectors for transformers and similar distribution equipment in power networks. Its scope fits installations that use high-voltage connections on the primary side and low-voltage connections on smaller units, including 240/120 V service arrangements. It may also be referenced during manufacturing, inspection, and procurement of connector hardware for utility and industrial electrical systems where standardized voltage connector requirements are needed.
Why is C57.12.23-1992 important?
This standard matters because voltage connectors must perform reliably under defined electrical conditions, and inconsistent connector design can increase safety and compatibility risks. C57.12.23-1992 supports clearer engineering decisions by giving buyers, designers, and test personnel a common reference for ratings and construction expectations. It can help reduce mismatches between equipment parts, improve interchangeability, and support acceptance testing and documentation for power equipment. For organizations handling older designs, the standard also provides a recognized basis for review.
