Motor

Typical Rack Assembly



Racks

Self-contained Modules with specific protection and control equipment have been wildly accepted and in use in many electrical utilities throughout North America. Based on the advantages the modular system brings to the engineering and design of a substation, CLA has developed and tested its own modular system.

Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack mounted system, a rack mount chassis, sub rack, rack mountable, or occasionally simply shelf.

Modules

Each module is designed for a specific function either protection, control, metering, or data acquisition. Each Module comes with and a module layout, bill of materials, ac/dc schematics, wiring and logic diagrams and nameplates for all devices within that module.

All device connections associated with the main module device are wired out to terminal blocks located on the sides of the panels. The terminal blocks are run continuously down the side panels with internal wiring facing into the devices and external cables terminated on the outside of the terminal blocks.
