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.
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.
Substation: This is the part dealing with the different entities of a substation including various devices, interconnections and other functionalities. The elements include power transformers, Voltage Levels, bays, General Equipment, conducting equipment like breakers.
Substations may perform many different functions but usually transform voltage from low to high (step up) and from high to low (step down). Between the generator and the final consumer, the voltage may be transformed several times. [25] The three main types of substations, by function, are: [26]
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 ...

Earlier in the day, an equipment failure at a substation in Waretown left 13,000 customers without power in Waretown and Barnegat, said Christopher R. Hoening, a JCP&L spokesman. “We were able ...
An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. [1] It converts direct current to alternating current or the reverse.
