Introduction This introduction is not part of IEEE Std C57.148-2011, IEEE Standard for Control Cabinets for Power Transformers. This standard is intended to provide requirements for the design and manufacture of cont

3、rol cabinets for Class I and Class II power transformers. The standard also contains options to cover the various types of components that could be provided, the various types of cooling classes that may be employed, and the various site-specific or user-specified requirements that may exist for the

4、 transformer. Notice to users Laws and regulations Users of these documents should consult all applicable laws and regulations.

Overview 1.1 Sco

38、pe 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 will apply to Class 1 and Class 2 power tran

39、sformers and will not apply to distribution or padmount design transformers. 1.2 Purpose This document will provide 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

40、users to review control cabinet designs. 2.
