A substation is an electrical installation that serves as a switchyard for high-voltage power lines. Substations may also contain other equipment such as transformers, capacitor banks, and load tap changers. The primary purpose of a substation is to switch electricity between different parts of the electric grid.
Substations are an important part of the power grid. They help to regulate voltage and keep the flow of electricity flowing smoothly. Without substations, the power grid would be much less reliable.
There are a variety of different types of substation equipment, each with its own purpose. The most important pieces of equipment are the transformers, which convert high-voltage electricity into lower voltages that can be used by homes and businesses. Other important equipment includes breakers, which protect against overloading, and switches, which control the flow of electricity.
Substations play a vital role in keeping our lights on and our devices charged. Without them, we would be living in a very different world.

As the name suggests, a substation is an installation where equipment is used to change the voltage level of electrical power. A typical substation consists of transformers, switches and other devices which are connected together by busbars and cabling. The primary function of a substation is to switch electrical power from one circuit to another, or to change the voltage level of power so that it can be used on a different system.
Substations come in a variety of shapes and sizes, from small installations with just a few pieces of equipment, to large complexes with hundreds of devices. The size and complexity of a substation depends on the demands placed on it by the electricity network. For example, a simple distribution substation might have only two or three transformers connected together by busbars, whereas a complex transmission substation could have dozens of transformers interconnected by a maze of cabling.
The most important piece of equipment in any substation is the transformer. Transformers are used to change the voltage level of electrical power, either by stepping it up (increasing the voltage) or stepping it down (decreasing the voltage). This is done using coils of wire wrapped around an iron core; when an alternating current flows through these coils it creates a magnetic field which induces an electromotive force in secondary winding coils within the transformer.
This process increases or decreases the voltage depending on whether there are more turns in the secondary winding than in the primary winding (stepping up), or vice versa (stepping down).

Substation Equipment List
Substation Equipment List
A substation is a crucial part of the electrical grid, and there are many different types of substation equipment that work together to keep the power flowing. Here is a list of some of the most important pieces of equipment found in a substation:
* Circuit breakers – These devices are used to open and close circuits, and they play an important role in protecting equipment from damage due to overloads or faults.
* Transformers – Transformers convert alternating current (AC) into direct current (DC), or vice versa, and they are used to step up or down the voltage levels in a circuit.
* Capacitors and reactors – Capacitors store energy in an electric field, while reactors provide inductance in a circuit.
Both types of equipment help regulate the flow of electricity.
* Busbars – Busbars are made of metal conductors that carry large amounts of current between different parts of the substation.
* Insulators – Insulators are used to prevent electrical currents from flowing where they are not supposed to, and they play an important role in ensuring safety around live electrical equipment.

What Equipment is Used in Substation?
A substation is a critical part of the electrical grid. It is a junction point where high-voltage transmission lines meet and connect to lower-voltage distribution lines. Substations are also where voltage is transformed from one level to another.
All of this makes substations very important, and they must be designed and built with safety in mind.
There are many different types of equipment used in substations, but some of the most important are transformers, circuit breakers, and voltage regulators.
Transformers are used to change the voltage of electricity passing through them.
This is done by using coils of wire to induce a magnetic field. The strength of the magnetic field can be increased or decreased by changing the number of turns on the coil or by changing the amount of current flowing through it. Transformers can either increase or decrease voltage, depending on how they are wired.
Circuit breakers are devices that open and close electrical circuits. They interrupt the flow of electricity when there is an overload or short circuit, preventing damage to equipment and injury to people. Circuit breakers can be manually operated or they can be automated so that they trip if a problem is detected.
Voltage regulators are devices that maintain a constant voltage level despite fluctuations in the supply voltage. They do this by either increasing or decreasing the resistance in an electrical circuit. Voltage regulators may use electronic components such as transistors or thyristors, or they may use mechanical devices such as tap changers.
What is the Main Function of Substation?
A substation is an assembly of equipment for transforming, switching, controlling and protecting electrical energy. The primary function of a substation is to switch or distribute electricity at high voltages so that it can be used by consumers. A substation also regulates the voltage and controls the flow of electricity.
What is the Difference between a Substation And a Transformer?
A substation is an electrical installation where voltage is transformed from high to low, or the reverse. A transformer is a device that transforms energy from one form to another.
Why is a Substation Called a Substation?
A substation is an electrical installation where power from high voltage transmission lines is transformed to a lower voltage for distribution. The word “substation” can be used to refer to either the entire facility, or just the transformer itself.
The first large scale electric power system was designed and built by Thomas Edison in 1882.
His Pearl Street Station in New York City used direct current (DC) electricity, which could only be transmitted a few miles before it began to lose strength. In order to transmit electricity over long distances, alternating current (AC) became the standard. However, AC cannot be directly utilized by most devices and appliances; it must first be converted back into DC.
This conversion is done using a device called a rectifier, which converts AC into DC via a process of rectification.
Rectifiers were originally large, expensive pieces of equipment that had to be located at the end user’s premises. As demand for electricity increased, it became impractical to have so many rectifiers spread out across the city.
To solve this problem, utilities started building central stations where multiple lines from different parts of the city converged. These central stations housed giant transformers that stepped down the voltage from high-voltage transmission levels (typically 115 kV or more) to medium-voltage distribution levels (usually between 4 kV and 34 kV). The use of transformers made it possible to distribute electricity over much longer distances with minimal loss in strength.
Substations are typically named after their primary function: Transmission Substation steps down high-voltage transmission line voltages to lower voltages for distribution; Distribution Substation steps down medium-voltage circuit voltages supplied by Transmission Substations for local distribution; and Service Substation provides low-voltages direct current for customer loads requiring less than 1000 volts DC such as street lighting systems or industrial processes..
Conclusion
Substation equipment is used to connect two or more pieces of electrical equipment. This can be done by using either an open or a closed circuit. The former is used when the voltage between the two pieces of equipment is low, while the latter is used when the voltage between the two pieces of equipment is high.
