A substation transformer is a type of power transformer that is used to step down the voltage from the high-voltage transmission line to the low-voltage distribution line. The substation transformer also steps up the voltage from the low-voltage distribution line to the high-voltage transmission line.
A substation transformer is a type of power transformer that is used to step down the voltage in an electrical grid. The primary function of a substation transformer is to convert high-voltage electricity from transmission lines into lower voltages that can be used by consumers.
Substation transformers are typically installed at the edge of an electrical grid, where the voltage needs to be reduced before it enters homes and businesses.
These devices play a vital role in ensuring the safe and reliable delivery of electricity.
There are many different types of substation transformers, each designed for specific applications. Some common types include oil-filled transformers, cast resin transformers, dry-type transformers, and air-cooled transformers.
Oil-filled transformers are the most common type of substation transformer. They are filled with a dielectric oil that helps to cool and insulate the winding coils. This type of transformer is typically used in medium or large scale applications.
Cast resintransformers are another popular type of substation transformer. They use epoxy resin to encapsulate the windings, which helps to protect them from moisture and other environmental factors. Cast resintransformers are often used in outdoor applications where they may be exposed to harsh conditions.
Dry-type transformers do not use any oil or other liquid for cooling purposes. Instead, they rely on air circulation to keep the winding coils cool.
Pad-Mounted Vs Substation Transformer
There are two main types of transformers used in the electric power industry: pad-mounted and substation. Pad-mounted transformers are small, self-contained units that are installed on a concrete pad or metal stand near the point of use. Substation transformers, on the other hand, are large units that are installed within a substation.
The main difference between these two types of transformers is their size and capacity. Pad-mounted transformers range in size from 25 kVA to 10 MVA, while substation transformers can range up to hundreds of MVA. The larger size and capacity of substationtransformers allows them to serve a much larger area than pad-mountedtransformers.
Another difference between these two types of transformers is their cooling method. Pad-mountedtransformers typically use air cooled fans, while substationtransformers use oil coolant systems. The different cooling methods help to keep each type of transformer at its optimal operating temperature.
When it comes to choosing between a pad-mounted or substation transformer, there are several factors to consider. The most important factor is the amount of power that needs to be delivered to the customer. If a customer requires a large amount of power, then a substation transformer will be needed.
If a customer only requires a small amount of power, then a pad-mounted transformer may be sufficient.
Substation Transformer Manufacturers
Substation transformer manufacturers are responsible for the design and manufacture of transformers used in electrical substations. A substation transformer is a specialized type of power transformer that is designed to step up or step down the voltage of an electrical system. The most common types of substation transformers are air-cooled and oil-cooled.
Air-cooled substation transformers are typically used in lower-voltage applications, while oil-cooled transformers are used in high-voltage applications. Some manufacturers also offer specialitytransformers, such as those designed for use in nuclear power plants.
The global market for substation Transformers was valued at $8.3 billion in 2016 and is expected to reach $11.5 billion by 2025, growing at a CAGR of 3.6% from 2017 to 2025, according to a report by Transparency Market Research.
The Asia Pacific region is expected to lead the global market due to the increasing demand for electricity in countries such as China and India.
Some of the leading companies in the global substation transformer market include ABB Ltd., Siemens AG, General Electric Company, Crompton Greaves Limited, Eaton Corporation PLC, and Toshiba Corporation.
Substation Transformer Specification
A substation transformer is a key piece of equipment in the electrical power system. It is used to step-down high voltage transmission line voltage to a lower distribution voltage used by customers. The substation transformer also provides isolation between the high voltage transmission circuit and the lower voltage distribution circuit.

Types of Substation Transformers
A substation transformer is a device that transforms high-voltage electricity from the power grid into lower voltages, which are then used by homes and businesses. There are three types of substation transformers: step-up, step-down, and isolation.
Step-up transformers increase the voltage of electricity before it enters the power grid.
This transformation allows electricity to travel long distances without losing power. Step-down transformers reduce the voltage of electricity after it leaves the power grid. This transformation makes electricity safe to use in homes and businesses.
Isolation transformers block the flow of direct current (DC) between two circuits. This prevents DC from damaging sensitive equipment like computers.
Substation Transformer Price
Substation transformer prices can vary greatly depending on the type, size and manufacturer of the transformer. The most important factor in determining the price of a substation transformer is the voltage rating. The higher the voltage rating, the more expensive the transformer will be.
Other factors that can affect substation transformer prices include the number of phases, frequency and efficiency.
Substation Transformer Function
A substation transformer is a type of power transformer that is used to step-down the high voltage from transmission lines to a lower voltage for distribution purposes. A typical substation transformer has three windings, with the primary winding connected to the high-voltage transmission line, the secondary winding connected to the low-voltage distribution line, and the tertiary winding connected to a ground (or earth). The primary and secondary windings are usually wound on separate cores in order to minimize leakage inductance between them.
The function of a substation transformer is to change (or transform) the voltage level of an alternating current (AC) electrical power system. In order for this transformation to take place, there must be a difference in voltage between the “from” side (high voltage) and “to” side (low voltage) of the transformer. This difference in voltages causes an induced electromotive force (emf) across the conductor loops or windings within the transformer coils.
As AC current flows through these coils, it magnetically induces a magnetic field within each coil. It is this magnetic field that couples together both sides of the transformer so that energy can be transferred from one side to another. The amount of energy that can be transferred is dependent upon many factors including:
– The number of turns in each coil or winding
– The cross-sectional area of each conductor loop
Substation Transformer Sizes
Substation transformers are an important part of the electrical grid. They help to step down high voltages from transmission lines and distribute power to homes and businesses. Transformers come in a variety of sizes, each with its own advantages and disadvantages.
Small substation transformers are typically less expensive than larger ones. They also have a smaller footprint, making them more convenient for installations where space is limited. However, small transformers can only handle so much power before they need to be replaced or upgraded.
Medium-sized substation transformers are a good compromise between size and cost. They can handle more power than small units, but are still relatively affordable. These units are often used in areas with moderate electricity demand.
Large substation transformers are the most expensive option, but they can provide power for even the most demanding applications. These massive units can last for decades with proper maintenance, making them a wise investment for utilities that require reliable service.

Which Transformer is Used in Substation?
There are many transformers used in substations, but the most common is the power transformer. This type of transformer is used to step up or step down voltage levels in order to match the voltage levels required by the equipment in the substation. The power transformer is typically a three-phase transformer, but there are also single-phase and two-phase transformers used in some applications.
What are the 3 Types of Transformers?
The transformer is a device that is used to transfer electrical energy between two or more circuits through electromagnetic induction. The transformer operates on the principle of Faraday’s law of induction, which states that when a conductor is moved in a magnetic field, an electromotive force (EMF) is induced in the conductor.
Transformers are classified according to the type of winding used in their construction.
The three main types of transformers are:
1) Auto-transformer: An auto-transformer has only one winding. The primary and secondary windings are electrically connected together, forming a single continuous circuit.
Energy is transferred between the primary and secondary windings by means of mutual inductance. Auto-transformers are typically used for voltage regulation or impedance matching.
2) Isolation transformer: An isolation transformer has two separate windings that are not electrically connected together.
Energy is transferred between the primary and secondary windings by means of mutual inductance. Isolation transformers are used to isolate electronic equipment from the mains supply or to provide electrical isolation between two circuits.
3) Step-up transformer: A step-up transformer has a primary winding with fewer turns than the secondary winding.
This causes the voltage across the primary winding to be lower than the voltage across the secondary winding, resulting in a step-up in voltage from primary to secondary side. Step-up transformers are used in power distribution systems to increase voltages from generation level (low voltages) up to transmission level (high voltages).
What is the Difference between a Substation And Transformer?
A substation is an electrical installation where voltage is transformed from high to low, or the reverse, using transformers. A transformer is a device that changes the voltage of an alternating current (AC) without changing its frequency.
How Many Transformers are in a Substation?
How many transformers are in a substation?
The answer to this question depends on the size of the substation. A substation can have anywhere from one to several transformers, depending on the amount of power that needs to be transferred.
The number of transformers also varies depending on the voltage levels being used. For example, a substation that uses high-voltage lines will need more transformers than one that uses lower voltage lines.
