IEEE C57.148-2020 PDF

This standard will provide minimum and optional function, layout, and construction requirements for standard control cabinet designs. It will also include a coding system for specifying standard control cabinets with the required options. This standard applies to Class I and Class II power transformers and does not apply to distribution or padmount design transformers. This document provides users and manufacturers with a set of standard designs that can be easily specified. The document should greatly reduce the engineering time required by manufacturers to create and by users to review control cabinet designs. Revision Standard - Active. Requirements for the design and construction of control cabinets on power transformers are covered by this standard.
