What is an electric substation?

The electrical substation is the type of installation located in most energy grids. Each electrical substation can perform a number of different functions such as redirecting the transfer voltage up or down. Each three main types of wiring are engaged in a specific aspect of grids, such as long -distance transmission, distribution to households and businesses, and collection from distributed systems such as wind farms. Electrical wiring is often large above earth installations with a highly visible device and a grounded fence, although they can also be underground or contained inside buildings.

In the first days of production and distribution of electricity, each local system was usually closed from others. These systems tend to have one or more power plants that had several wiring that helps in energy distribution. Today, the power grille tends to be a much less centralized system, although transmission and distribution devices are still commonly referred to as wiring. These substations are responsiblefor adjusting the voltage, distribution or collection of power lines and providing a way to insulate parts of the grid for diagnostic or repairs.

The simplest type of electrical substation is usually connected to electricity transmission over long distances. These transmission wiring often consists only of high -level switches, if the lines that connect, use the same voltage level. In other cases, it includes transformers' transmission. The electrical substation near the power plant will usually have increased transformers that will increase the voltage and reduce the current, which is a more efficient way of transmitting energy over long distances. Multiple transmission wiring is often placed along long routes to ensure insulation in the event of failures.

Distribution substations are often found nearby. This type of electrical substation usually includes a number of step transformers to reduce the transfer voltage and distributeAnd it between different feeders. These often are among the largest and most complex wiring, because they usually have high voltage lines and leave even more.

Some types of energy production also use the type of electrical substation known as a collector. These devices are somewhat reverse of distribution distribution, as they collect a number of lower voltage sources into one or more high -voltage outputs. Wind farms are one type of energy production equipment that can include a large number of generators spread over a large area. The collector's substation is usually able to collect these output lines together and supply electricity to the grid.
