Unit substation | unit substation transformer | Eaton example, the close-coupled design allows the transformer and electrical equipment to be located in close proximity to the load concentration, which minimizes the lengths of cabling and buses to reduce power losses and exposure to faults. This close-coupled design can also improve voltage regulation and service continuity.

Back to basics: Switchgear, transformers and UPSs· In a typical installation, LV switchgear is connected to the secondary of a power transformer — either the utility's service transformer or a facility transformer. Where service is at medium voltage, a power transformer may be close-coupled to the switchgear, with the two assemblies bolted together to form a single unit.
