Southwest Substation | Electrical Consultants Inc.
The Southwest Substation is a complete renovation of an existing 46-12.5 kV substation. The existing substation was a low profile sub that had reached the end of its lifecycle.
Customizable secondary unit substations are used to step down utility distribution voltage to in-plant distribution voltages when primary voltage classes are below 38 kV and secondary voltage classes range from 208 V to 600 V.
They can be applied inside or outdoors and consist of a close-coupled assembly made up of three main parts: There are two types of unit substations: primary unit substations and secondary unit substations. The two configurations are defined by equipment voltage, rating of the transformer and the type of equipment incorporated within the assembly.
The two configurations are defined by equipment voltage, rating of the transformer and the type of equipment incorporated within the assembly. The transformer is the major component of the assembly and understanding what type of technology to specify might be the most important design consideration when planning a unit substation assembly.
The assembly can incorporate electrical and control equipment including, but not limited to: Unit substations provide many advantages compared to traditional approaches of stepping down utility distribution voltages.
