An industrial substation is a facility where electricity is generated and distributed to factories, businesses, and other commercial facilities. The substation transforms high-voltage power from the utility company’s transmission lines into the lower voltages needed by the customers.
What is substation and its types | सबस्टेशन क्या होता है और इसके प्रकार?
An industrial substation is a type of electrical substation that is used for the distribution of power in an industrial area. It is usually located near the point of use, such as a factory or power plant, and provides electricity to business and residential customers in the area. The substation may be owned and operated by the local utility company, or it may be privately owned.
Underground Substation
An underground substation is a type of electrical substation in which the majority of the equipment is located below ground. This includes the transformer, switchgear, and associated control and protection devices.
The main advantage of an underground substation is that it takes up less space than a traditional above-ground substation.
This can be important in urban areas where land is at a premium. In addition, they are typically more aesthetically pleasing than their above-ground counterparts and can blend in better with their surroundings.
Underground substations also have some disadvantages.
They are typically more expensive to build than above-ground substations due to the increased complexity involved. In addition, they can be more difficult to maintain since all of the equipment is located below ground.
Distribution Substation
A distribution substation is a substation that takes power from the transmission grid and delivers it to the local distribution network. It is typically located at the edge of the distribution network, close to customers.
The main components of a distribution substation are transformers, switchgear, circuit breakers, and metering equipment.
The transformers change the voltage of the electricity so it can be used by homes and businesses. The switchgear controls the flow of electricity and protects equipment from overloads. Circuit breakers shut off power in case of an emergency.
Metering equipment measures how much electricity is being used.
Distribution substations play an important role in keeping power flowing to homes and businesses. Without them, we would not have lights, heat, or any of the other conveniences that come with electricity.
Types of Substation
An electrical substation is a crucial part of the power grid. It is where electricity is generated, transformed and then distributed to homes and businesses. Substations come in a variety of shapes and sizes, but all serve the same purpose.
The two main types of substations are transmission substations and distribution substations. Transmission substations connect high-voltage power lines that carry electricity over long distances. These substations step up the voltage of the electricity so it can travel across great distances without losing power.
Distribution substations connect lower-voltage power lines that distribute electricity to homes and businesses within a smaller area. These substations step down the voltage of the electricity so it can be used safely in our homes and businesses.
Whether it’s a transmission or distribution substation, each one contains several key components:
* Transformers – change the voltage level of the electricity
* Circuit breakers – protect equipment from damage by opening circuits when there is too much current flowing
* Capacitors – store energy temporarily to help regulate voltage levels
* Disconnect switches – open or close circuits as needed
* Metering devices – measure various electrical parameters such as voltage, current, and power levels
Transformer Substation
A transformer substation is a type of electrical substation that transforms voltage from high to low, or the reverse. It is used to connect two parts of an electrical grid that have different voltages. The first part of the substation has a generator that creates electricity at a high voltage.
This electricity passes through transformers in the substation, which lowers the voltage so it can be sent safely through power lines to homes and businesses. The second part of the substation includes devices that raise the voltage back up before it reaches its destination.
Transformers are essential for ensuring stable electric power supply across long distances.
Without them, voltages would fluctuate too much and cause blackouts or damage equipment. Substations help regulate voltage levels and keep them within safe limits; they also protect against power surges by rerouting excess electricity away from sensitive equipment.
There are three main types of transformer substations: step-down, step-up, and isolation.
Step-down transformers lower voltage while maintaining current, while step-up transformers do the reverse. Isolation transformers block any current from flowing between two parts of an electrical circuit; they’re typically used for safety reasons, such as when working on live wires.
Transformers come in a variety of sizes depending on their intended use; large ones can weigh hundreds of tons.
Substation Construction
As the demand for electricity continues to grow, so does the need for new substations. A substation is a critical part of the electrical grid, and its construction requires careful planning and execution.
There are several steps involved in constructing a substation, from site selection and preparation to setting up the equipment and commissioning the facility.
The first step is to select a suitable site for the substation. The location must be large enough to accommodate all of the equipment, and it must have easy access to an existing power source. Once a site has been selected, the next step is to prepare it for construction.
This includes clearing any trees or other obstacles from the area, as well as excavating trenches for underground cables.
After the site is ready, construction can begin on the actual facility. This usually involves erecting walls and roofs, as well as installing all of the necessary equipment.
Once everything is in place, testing can begin to ensure that everything is working properly. Finally, when everything is up and running smoothly, the substation can be officially commissioned and put into service.
Substation construction is a complex process, but it’s essential for keeping the electricity flowing throughout our communities.
Electrical Substation
An electrical substation is a facility where electricity is generated, transformed and distributed to consumers. It usually consists of transformers, switchgear and other equipment. The first substations were built in the early days of the electricity supply industry to provide a local source of power for homes and businesses.
Today, substations play a vital role in the distribution of electricity around the world.
Substations come in all shapes and sizes, from small rural installations to large urban facilities. They can be found underground, above ground or on top of buildings.
Substations can also be classified by their function, such as transmission substations or distribution substations.
Transmission substations are typically located near power plants or other large generation facilities. They step up the voltage of the electricity so it can be transmitted over long distances through high-voltage transmission lines.
Distribution substations reduce the voltage of electricity before it is delivered to homes and businesses through lower-voltage distribution lines.
Large Substations: 500 kV and Above
The largest electrical substations are usually built for high-voltage transmission systems carrying 500 kilovolts (kV) or more of electricity.
These massive installations typically cover several acres and may include dozens oftransformers as well as extensive switchgear for controlling the flow of power. Many high-voltage transmission substATIONS also have oil-filled capacitor banks that help regulate voltage levels on the system. One notable example is Arizona’s Hassayampa Electrical Substation which covers nearly 300 acres (1 square kilometer) and includes 36 500 kV transformers.

Transmission Substation
A transmission substation is a type of electrical substation that is used to switch or regulate the voltage in an electric power system. Transmission substations are typically located between the generating plant and the distribution substations, where the voltage is reduced for use by consumers.
The main components of a transmission substation are transformers, circuit breakers, and other equipment needed to control the flow of electricity.
The transformer changes the voltage of the electricity so that it can be sent long distances through high-voltage transmission lines. Circuit breakers are used to protect equipment from damage by interrupting the flow of electricity when there is a problem.
Transmission substations play an important role in ensuring that electricity flows smoothly and safely throughout the power grid.
Without these critical pieces of infrastructure, our modern society would not be possible.
Components of Substation
A substation is an electrical power facility where voltage is transformed from high to low, or the reverse, using transformers. Substations may also be used to switch circuit breakers and disconnectors in order to isolate equipment and circuits for maintenance purposes.
The three main components of a substation are:
– The transformer(s), which change the voltage level
– The switchgear, which controls the flow of electricity

What is the Purpose of a Substation?
A substation is an electrical installation where high-voltage power lines from the grid (the network of transmission lines that carry electricity from generating stations to consumers) are brought into contact with lower-voltage distribution lines that lead to customers. The purpose of a substation is thus to step down the voltage so it can be used safely by homes and businesses.
Substations come in all shapes and sizes, but most have a few key components in common.
These include:
· A control house: This is where personnel operate equipment that controls the flow of electricity through the substation.
· Circuit breakers: These devices protect equipment by automatically shutting off the flow of electricity when there’s a problem, such as a power surge.
· Transformers: These convert high voltages to lower voltages, or vice versa.
· Capacitors and reactors: These devices help improve power quality and maintain voltage levels within acceptable limits.
What is the Difference between Station And Substation?
In the electrical power industry, a station is a large facility that contains one or more generators, transmission and distribution equipment for electricity. A substation is a smaller facility where voltage is transformed from high to low, or the reverse.
The main difference between a station and substation is their size.
A station takes up a large amount of space because it houses one or more generators while a substation only needs enough space to house its transformer (or transformers). The other big difference between these two facilities is what they do. A station generates power while a substation simply transforms it.
Why is a Substation Called a Substation?
A substation is an electrical installation where power from a high voltage transmission system is switched to a lower voltage distribution system. The word “substation” can also refer to the building or structure that houses the equipment, or even just the equipment itself.
The term “substation” comes from the days when electricity was first being generated and transmitted on a large scale.
The early power plants were often located some distance from the load centers they served, so it was necessary to build smaller stations along the way to step down the voltage for local distribution. These local substations became known simply as “substations.”
Today, most substations are still used to switch power from transmission to distribution voltages, but they can also be used for other purposes such as monitoring and protection of high voltage circuits, transformation of voltages (for example, changing 13,800 volts to 240 volts), or isolation of sections of networks.
What are Types of Distribution Substations?
A distribution substation is a facility where voltage from a transmission line is lowered to the level used by customers, and also may include equipment for switching, protection and/or control of the distribution system. The types of distribution substations are:
-Pad-mounted switchgear: This type of substation houses all electrical equipment in weatherproof enclosures on or near the ground.
-Recessed pole switchgear: This type of substation has buried primary conductors and secondary feeders coming up through underground ducts to recessed service boxes at each pole.
-Cabinet switchgear: This type of substation uses cabinets that are placed on concrete pads or vaults. All equipment is located inside these cabinets.
Conclusion
An industrial substation is a type of substation that is typically used to distribute power to large industrial facilities. These facilities can include factories, mines, and other types of plants. Industrial substations are usually located near the load center so that they can provide power directly to the equipment that needs it.
