In a substation, all equipment is connected to the high-voltage busbars. The main switchgear consists of circuit breakers and disconnectors. Circuit breakers are used to connect or disconnect parts of the substation from the high-voltage network.
Disconnectors are used to isolate circuit breakers and other equipment from the high-voltage system for maintenance purposes.
The current transformers (CTs) and potential transformers (PTs) in a substation measure the currents and voltages in the high-voltage network. The CTs and PTs provide signals that are proportional to the currents and voltages in the network for use by relays, meters and other control equipment.
The earthing system in a substation provides a low impedance path to earth for fault currents. This ensures that circuit breakers can quickly clear faults on the high voltage system.
Substation Components And Their Functions Ppt
A substation is a crucial part of the electrical grid. It is where high-voltage transmission lines meet lower-voltage distribution lines and where electricity is transformed to a different voltage for use in homes and businesses. Substations come in a variety of shapes and sizes, but all have certain key components.
The first component of a substation is the transformer. The transformer changes the voltage of the electricity passing through it, either increasing or decreasing the voltage as needed. Transformers can be air-cooled or oil-filled, and use either cores made of iron or coils of wire to increase or decrease the voltage.
The second key component of a substation are the breakers. These massive switches regulate the flow of electricity into and out of the substation, and can rapidly shut off power in case of an emergency. Breakers are usually located near the top of substations so that they are easily accessible for maintenance.
Substations also have busbars, which are metal bars that conduct electricity between circuit breakers, transformers, and other equipment within the substation. Busbars are often made from copper or aluminum because these metals have high electrical conductivity rates. Finally, every substation has at least one control house where operators can monitor equipment and make sure everything is running smoothly.

132 Kv Substation Equipment Pdf
If you’re in the process of planning or building a 132 kV substation, then you’ll need to be aware of the various types of equipment that are typically used. This blog post will provide an overview of some of the most common pieces of equipment found in 132 kV substations, as well as their purpose and function.
One of the most important pieces of equipment in any substation is the switchgear.
The switchgear is responsible for controlling the flow of electricity within the substation, and it can be either manually operated or automated. If you’re opting for automation, then you’ll need to choose between air-insulated switchgear (AIS) or gas-insulated switchgear (GIS). AIS is typically more expensive than GIS, but it offers a number of advantages, such as a smaller footprint and lower maintenance costs.
The next piece of equipment you’ll need to consider is the transformer. The transformer steps down the voltage from the incoming power lines so that it can be used by the equipment within the substation. There are two main types of transformers – dry-type and oil-filled – and each has its own benefits and drawbacks.
Dry-type transformers are less expensive and easier to maintain, but they’re not suitable for use in all environments. Oil-filled transformers are more expensive, but they’re better able to withstand extreme temperatures and conditions.
Another important piece of equipment found in many substations is circuit breakers.
Circuit breakers protect both people and equipment by automatically disconnecting power when an overload or fault is detected. They come in both high voltage (HV) and low voltage (LV) varieties, so make sure you choose one that’s appropriate for your needs.
Finally, every substation needs some sort of monitoring system so that operators can keep tabs on what’s happening inside.
This could be anything from a simple set of meters to a more sophisticated supervisory control and data acquisition (SCADA) system.
Electrical Substation Equipment
An electrical substation is a critical part of the electric grid. It is a collection of equipment that connects two or more circuits together, usually at different voltages. The most common type of substation in North America is the transformer substation.
Transformers are used to change the voltage of electricity so it can be sent over long distances without losing power. A typical transformer has three windings: the primary winding, which receives electricity at high voltage from the power line; the secondary winding, which transforms the voltage to a lower level; and the tertiary winding, which provides a third voltage level if needed.
The transformer is just one piece of equipment in a substation.
Other components include circuit breakers (which protect transformers and other equipment from damage due to overloads or faults), current transformers (which measure currents), potential transformers (which measure voltages), capacitor banks (which store energy), and busbars (metal bars that conduct electricity).
Substations vary in size and complexity depending on their purpose. Some are very large with many pieces of equipment, while others are smaller and may have only one or twotransformers.

What Equipment is Found in a Substation?
The equipment found in a substation can vary depending on the size and purpose of the substation. However, there are some common pieces of equipment that are typically found in most substations.
One piece of equipment that is found in nearly all substations is transformers.
Transformers are used to step down or step up voltages as needed. This is important because the voltage coming from the power plant will be too high for distribution to homes and businesses. The transformer steps down the voltage so it can be used safely.
Another common piece of equipment found in a substation is circuit breakers. Circuit breakers protect electrical equipment from damage by breaking the circuit if there is an overload of current. This prevents fires and other damage that could occur if too much electricity was flowing through a system.
Other common pieces of equipment found in substations include:
– Capacitors: Used to store energy and improve power factor
– Reactors: Used to limit current flow
– Disconnect switches: Used to isolate sections of the electrical grid for maintenance or repair
– Grounding devices: Used to provide a safe path for excess current to travel
Depending on the purpose of the substation, there may be other specialized pieces of equipment as well.
For example, if a substation is used for regulating voltage, then it may contain devices like tap changers or Thyristor controlled reactors (TCR).
What is Electrical Substation Details?
An electrical substation is a facility where electricity is generated, transformed and distributed to consumers. It may also be known as a power plant, a generating station, or a power center. A substation can be as simple as a single transformer that steps down the voltage of an incoming transmission line to the level needed by local distribution lines.
Or it can be much more complex, containing several transformers, generators, switchgear and other equipment necessary to change both the voltage and frequency of electricity before it is delivered to customers.
Incoming high-voltage transmission lines are connected to transformers that reduce the voltage so it can be used on lower-voltage distribution lines within the substation. The outgoing distribution lines from the substation may connect directly to customer loads or may feed into lower-voltage transmission lines that deliver electricity over long distances before stepping down the voltage again at another substation closer to customers.
Substations are usually located near load centers such as cities or industrial areas. They may also be located along transportation routes so electricity can be delivered quickly and efficiently to customers.
Which Information We Can Get from Substation Equipment Diagram?
As its name suggests, a substation equipment diagram provides detailed information about the equipment used in a substation. This includes everything from the transformers and switchgear to the cabling and busbars. By understanding all of the different components of a substation, engineers can more effectively troubleshoot problems and keep the facility running smoothly.
Each piece of equipment in a substation has its own unique function, so it is important to be familiar with what each one does. For example, transformers are used to step up or step down voltages, while switchgear controls the flow of electricity within the substation. Other common pieces of equipment include circuit breakers, fuses, and grounding rods.
In addition to knowing the function of each piece of equipment, it is also important to understand how they are interconnected. The layout of a substation can vary depending on its purpose and size, but there is always a clear connection between all of the different components. By studying a substation equipment diagram, engineers can better understand how power flows through a facility and identify potential bottlenecks or areas where improvements can be made.
What is the Main Components of Sub Station?
A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltages.
A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages. Substations may be owned and operated by an electric utility company, independent electricity supplier, or customer.
