These substations may consist of two to eight or more primary transformers connected to the same secondary bus to provide reliable facility power. Examples of such single facilities include airports, hospitals , major data processing centers (especially those using uninterruptible power supplies ), and sports arenas that regularly broadcast ...
A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.
A view of the substation from the Monroe Street Bridge. The Post Street Electric Substation was designed by Kirtland K. Cutter for the Washington Water Power Company [3] and constructed in 1910 to serve as a low-tension distributing and converting station and as Washington Water Power's primary substation in Spokane.

A substation is “a high-voltage electric system facility,” OSHA says, where power — specifically, voltages — becomes suitable for distribution and supply to customers.
Most of the world uses 50 Hz 220 or 230 V single phase, or 400 V three-phase for residential and light industrial services. In this system, the primary distribution network supplies a few substations per area, and the 230 V / 400 V power from each substation is directly distributed to end users over a region of normally less than 1 km radius.
A traction substation, traction current converter plant, rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or ...

The PRR substation architecture was based on a long-distance, high-speed railway. The substation spacing ensures that any train is never more than 4 or 5 miles from the nearest substation, which minimizes voltage drop. One disadvantage to the substation design as originally built by the PRR concerns its lack of 138 kV circuit breakers.
