Back to basics: Switchgear, transformers and UPSs· 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. The resulting assembly is called a "unit substation." The distribution breakers of the switchgear will typically serve feeders to large facility loads, such as chillers, large ...
