Most organizations tend to operate with the support of a substation. The organization needs to ensure regular maintenance of the substations as many challenges can affect the substations' operations, causing a delay in the delivery of services to the consumers. Faulty substations can affect an organization's operations and how the consumers get their power in a specific region. When the substation equipment is faulty, its performance and reliability tend to be affected, and they can be dangerous to the people who are using them. Therefore, it is essential for the organizations that use substations to identify reliable substation maintenance companies that they can always call for maintenance of their equipment. If you do not understand the importance of having regular substation maintenance, read through this article and get a glimpse of what it means to have substation equipment maintenance and the role that the substation maintenance companies play during the maintenance.

What is a Substation?

A substation is a high voltage capacity electrical system used to control electrical circuits, generators, and other equipment. A substation is used to change the voltage from high to low, and you can also use it to generate, transmit and distribute electrical voltage. Substation use can help reduce the high voltage of electrical power transmitted to make it suitable for the customer's use. In the substation, different equipment is used to help in the transmission and generation of electrical power. There are transformers used to change the voltage levels in the substation and circuit breakers used to protect the electrical circuit from any damage caused by overloads of power in the substation. Most of the time, the substations are remotely managed and controlled, as there is a lot of power transmission. Substation maintenance companies can be owned and managed by an electrical utility or a commercial customer.

Types of Substations

There are different types of substations. They are classified depending on their voltage levels, applications within the power system, the types of insulations used in the connections, and the materials and styles used to structure them. They include:

1. Distribution Substation

These substations transmit power from the transmission system to the distribution system within an area. They are mainly placed in areas with an extensive network of consumers who need a high distribution of voltages. A distribution substation helps to save on the direct connectivity of the consumer to the leading transmission equipment, as they reduce the power voltage to a distribution level that can be used by the consumer, especially those who do not use a tremendous amount of power. The distribution substations transmit medium voltages that range from 2.4kV and 33kV depending on the number of consumers within a specific region.

The substations also isolate any faults detected in the transmission or distribution systems that might affect how consumers get their power. The distribution substations have been created to have a transformer and a switch that you can use to regulate the high voltage to ensure they are at the best levels for the consumers. There are many pieces of substation equipment placed in the distribution substation to help effectively supply power to many consumers that depend on the distribution substations.

2. Underground Distribution Substation

These types of substations are installed underground to help reduce the space problems in the urban areas. They are used to supply high voltage electricity in the urban areas without any interruption and usage of huge spaces. The substations are environmentally friendly, and they help save on space as they are placed underground. They help protect the consumers from dangers brought about by substations placed in highly congested regions within the cities and provide surface-built solutions for power. They provide all the functionalities of a substation and help save on the space used in the different areas where the substation is installed. Underground distribution substations are considered more effective, especially when placed in highly populated regions, as they effectively meet the needs of the consumers and still utilize as little space as possible during the installation.

3. Step-Up Transmission Substation

The step-up transmission substation uses the power supply from a nearby company producing power. It mainly uses big power transformers to enhance the voltage level needed to be transmitted to remote locations around the substation. The transmission bus is also used to distribute the electric power from the substation to other transmission lines. The step-up substation is also used to get incoming power from a distributor, where it is going to be received in a generation plant, and later, power is supplied to the consumers.

4. Step-Down Transmission Substation

These types of substations are located in different locations in an electrical network. They tend to connect different parts of the network, and they act as the source of the sub-transmission and distribution lines of the power to the consumer. The step-down transmission is used to change transmission voltage to sub-transmission, which is the best form that can be supplied to the consumers in the regions near the substations.

5. System Substation

These substations are used to transfer a huge amount of power to the network of consumers in a specific region. The substations are used to provide switching facilities as they do not use the power transformers. Also, they are essential for performing voltage conversion to make it more consumer-friendly. The system substations tend to be very expensive to construct and maintain. They are very large and provide different electrical circuits that feed the transforms with the necessary voltage easily transferred to the customer.

6. Customer Substation

These substations tend to supply electric power to one customer. They can be used for large organizations that use very high electrical voltages. These substations are built near the organizations that need them to ensure that they are the only consumers using them to help reduce the chances of any overload on the equipment. They are built depending on the consumer's requirements, where they look to meet the consumer's electrical power needs.

Elements of a Substation

A good substation has different components that help it in its functionalities. They will contain:

  • Surge protection

  • Earth or grounding system

  • High voltage switchgear

  • Circuit breaker

  • Disconnecting switch

  • Transformer to measure the electric voltage

  • Primary power lines

  • Overhead wires

  • Ground wires

  • Insulators and conductors

  • Fuses

Different Roles of a Substation

  1. The main role of substations is to reduce the high electricity voltage from the transmitting system and ensure that it gets to a lower level that the consumers can use without causing them any harm. The substations also ensure that the lower voltage electricity is distributed to the consumers through the distribution lines.

  2. Substations are also used to control equipment that generates and distributes electricity, circuit breakers, and transformers in different regions.

  3. The substations that serve high-level consumers who use more electricity tend to have circuit breakers used to regulate any overload that may occur on the network during the supply of power to the consumers.
