Substations can be categorized by their various functions and roles. Step-up substation - These substations raise the voltage from generators (usually at power plants) so electricity can be transmitted efficiently. For more information on why higher voltages are more efficient for the transmission of power, see electrical transmission.
The grid includes electricity substations, transformers, and power lines that connect electricity producers and consumers. Most local grids are interconnected to maintain reliability and for commercial purposes, forming larger, more dependable networks that helps suppliers consistently produce the right amount of electricity to meet demand
Substations are located throughout electric power transmission and distribution systems and serve a variety of functions, such as: Transmission system switching points. Voltage transformation and regulation. Sources of distribution circuits. Substations may be indoors or outdoors, and may be metal clad or open bus.
A step-up transmission substation receives electric power from a nearby generating facility and uses a large power transformer to increase the voltage for transmission to distant locations. A transmission bus is used to distribute electric power to one or more transmission lines. There can also be a tap on the incoming power feed from the
Introduction. An power substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high or medium to low or the reverse using
This substation uses large transformers to convert or "step up" the generator''s voltage to extremely high voltages for long-distance transmission on the transmission grid. Typical voltages for long distance transmission are in the range of 155,000 to 765,000 volts. The higher the voltage, the less energy is lost due to resistance [source: UCSUSA ].

Introduction The power grid is a complex, interconnected network that delivers electricity from producers to consumers. A key component of this network is the electrical substation - a type of installation that performs several critical functions in the power grid. Substations transform voltage from high to low, or vice versa, and perform
Substations used to step up or step down the voltage level of an AC power system for power distribution are commonly termed as transformer substations. Power Substations are usually located near
While identifying the power substation as part of the system for a generation project or as a part of distribution grid, preliminary site selection is done by the utility based on the shortest length of the incoming (incomer) and outgoing lines which are normally surveyed/marked on the 1:50,000 maps/topographical maps of the area with details about proximity to

The substations contain power transformers that reduce the voltage from sub-transmission levels to distribution levels, usually in the range of 4.16Y/2.4 kV to 34.5Y/19.92 kV. The transformers are normally equipped to regulate the substation bus voltage.
Function of Substations. While electric substations take part of the distribution of electricity, they have many other functions as follows: Step up and step down of the voltage for transmission and distribution. As power is transmitted at a higher voltage over long distances, the current is lower. This results in lower transmission losses but
