Power Transformer Definition

power transformers are static devices used for transforming power from one circuit to another, or for changing the voltage level in an electrical system. It works by transferring energy from one electric circuit to another through inductive coupling, which is achieved by the magnetic field created between two or more coils.

A power transformer consists of two primary and secondary windings, with the former providing power from one circuit and the latter taking this power and transforming it into a different voltage level.

Power transformers are commonly used in electrical systems for electric power distribution, as well as for providing protection against overvoltage or undervoltage. They are also used to isolate sensitive electronic devices from unexpected voltage surges. The efficiency of a power transformer depends on its design and quality of construction; hence it is important to select a model that meets your application’s requirements accurately.

What kind of materials used for producing oil immersed transformer?

Oil immersed transformers are one of the most commonly used electrical machines for power transmission and distribution. Within the transformer, the core and windings of these transformers are immersed in a high-grade mineral oil, which provides insulation and cooling to the transformer components.

The materials used for producing these transformers are extremely important as they determine the performance, efficiency and reliability of the equipment. The core is usually made up of high-grade cold rolled non-grain oriented electrical steel laminations, while the windings are made up of copper or aluminum conductor foils/tapes with polymer insulation layers.

The tank, bushings, fittings and other components are made up of durable materials such as cast iron or stainless steel that ensures structural integrity and weather resistance. In addition, the oil used must be carefully selected based on its dielectric strength, viscosity index and fire point properties to ensure safe operation of the transformer under all conditions.

How many types are there for power transformer?

Power transformers are a type of electrical device used to transfer electrical energy from one circuit to another. There are several different types of power transformers, depending on their purpose and the particular requirements of the application. Some of the most common types include three-phase transformer, auto-transformers, instrument transformers, distribution transformers, winding transformers and step-up/step-down transformers, but current transformers are not included.

different types of power transformer

Auto-transformers are used to change voltage levels without changing frequencies, while instrument transformers are used to measure currents and voltages. Distribution transformers decrease voltage levels before they reach buildings or devices, while step-up transformer and step-down transformers increase or reduce voltage levels as needed. Each type has its own unique features and advantages that make it suitable for specific applications.

It is important to choose the right type of transformer for any given situation in order to ensure that all safety standards are met and that no damage is done to any electrical components.

How the oil immersed electrical power transformer is made in the factory?

The high voltage electric power oil-immersed transformer is a type of distribution transformer that is commonly used in electrical power systems. It is made up of two sets of coils called the primary and secondary windings, which are wrapped around an iron core. The windings are then immersed in a tank filled with dielectric oil that serves to insulate and cool the transformer.

The dielectric oil also helps to reduce the chance of arcing in the coils. In the factory, these components are combined into one unit by winding the coils around a steel core and then immersing it in a tank containing the dielectric oil.

Once complete, this assembly is tested for electrical performance and safety before being released for use. The entire process requires great precision and care to ensure that the finished product meets quality standards and performs as expected.

Yes, you can customize power transformers according to the designs and demands. Power transformers are used for the efficient conversion of electric energy from one form to another. They come in various types such as distribution transformer, ideal transformer, power distribution, core type, etc. Depending on the application, the design and demand of a transformer can be customized accordingly.

This customization helps to reduce power loss which is necessary for maintaining an efficient electrical system. With modern technologies and advanced materials, customizing power transformers have become more reliable and cost-effective than ever before.

Oil immersed transformer used condition and environment

Oil-immersed transformers are one of the most widely used types of transformers in the world. They are commonly used in power distribution systems and phase networks, as they provide a cost-effective solution for electrical energy transmission over long distances. The main advantage of this transformer is its high efficiency, which is obtained by using oil as an insulating medium.

 Additionally, this kind of transformer does not require frequent maintenance and can operate in a range of environmental conditions. The temperature range within which it can be operated depends on the grade of oil and type of cooling system used. It is important to note that for optimal performance, these transformers should be stored in a dry environment and kept away from extreme temperatures and humidity. Additionally, regular testing should be carried out to ensure proper functioning of the equipment.


A distribution transformer is a critical component of an electrical grid. It takes a high voltage and step it down to a lower voltage, allowing it to be distributed in a safe and efficient manner. Without these transformers, many of the conveniences we take for granted today would not be possible.

 Consequently, careful consideration must be given to their design and installation in order to ensure optimal performance and reliability. In conclusion, distribution transformers are essential for modern life and should be properly designed, installed and maintained for maximum efficiency and safety.
