IEEE C57.148-2011 pdf free.IEEE Standard for Control Cabinets for Power 1 Transformers.
IEEE C57.148 will provide minimum and optional ftinction. 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 (‘lass I and (‘lass 2 power transformers 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 he easily specified. The document should greatly reduce the engineering time required by manutcturers to create and by users to review control cabinet designs.
2. Normative references
The following referenced documents are indispensable for the application of this document (i.e., they must be understood and used, so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments or corrigenda) applies.
3.1 Definitions
For the purposes of this document, the following terms and definitions apply. The IEEE Standards
Dictionary: Glossary of Terms & Definitions should be consulted for terms not defined in this clause.9 control cabinet: The primary cabinet(s) on a Class I or Class II transformer that contains the control panels for relay, metering, alarms, cooling controls, auxiliary power, and related circuits for user connection to the related systems in the substation.
control cabinet designer: The engineer or designer responsible for designing the layout and circuitry in the control cabinet.
DIN rail: A standard 35-mm-wide metal rail used to mount terminals, circuit breakers, and other types of devices (as specilied in DIN EN 50022).
fluorinated ethylene propylene (FEP): A compound used for wire and cable insulation and jackets.
ground fault interrupter (C Fl): A device commonly used for protection of personnel or some circuits by fast tripping tbr differential current in the neutral and phase wires of a circuit.
machine tool wire: A flexible, stranded wire with a polyvinylehloride (PVC) insulation and jacket compound.
niaiiufacturer: The organization that constructs or supplies the device or equipment.
piano hinge: A long hinge with one continuous pin, attached along the full available lengths of a door and frame. Also referred to as a continuous hinge.
positive temperature coefficient (PTC) heater: A type of heater that provides self-regulating temperature control resulting from the thermal-resistive properties of the ceramic materials used for the heating elements.
supplier: Refers to the transformer manufacturer when the control cabinet has been ordered by the transformer manufacturer, or refers to the control cabinet manufacturer when the control cabinet has been ordered directly from the control cabinet manufacturer by the user.
switchboard wire: A flexible, stranded, tin-coated wire, with a cross-linked polyethylene insulation and jacket compound.
user: The organization. or representative of the organization, who specifies and orders the purchase of the transfarmer and/or control cabinet and will own and operate the iransthrmer and/or control cabinet when it is received and placed in service. As used in the introductory sections before the Contents, the term refers to the user of this standard.
wire raceway: A channel, with or without a cover, designed to contain and route wires and cables adjacent to terminal blocks and other devices.IEEE C57.148 pdf download.
