Primary unit substations design guide

primary unit substation is a close-coupled assembly consisting of enclosed primary high-voltage equipment, three-phase power transformer and enclosed secondary medium-voltage equipment. The following electrical ratings are typical: Primary voltage: 6.9–69 kV. Transformer kVA: 500–20,000 kVA. Secondary voltage: 2.4 kV–34.5 kV.

Medium-voltage transformers: fundamentals of medium-voltage transformers

Substation transformers are rated by their primary and secondary voltage relationship and their power carrying capability. For example, a typical substation transformer would be rated 15 kV, 25 kV, 35 kV or 46 kV on the primary at a power rating of about 5-20 MVA.

The Role of a Station Transformer in a Power System

It is the station transformer that provides ''house'' power to a system, working the lights, fans, pumps, and more. Using its step-down capabilities, the transformer reduces the electricity from the grid – this filters through to the system as a whole. Once the activation process concludes, the station can switch power over to a generator
