Structure and Features of Power Transformers

9 May 2023

Power transformers are a type of transformer that enables the transmission of electricity without changing its frequency, only altering its magnitude. This type of transformer is composed of thin silicon steel sheets and is responsible for altering voltage values. It consists of a core and coils insulated with windings wound around the core.

Through power transformers, electrical energy can be transmitted over long distances without alteration. The electrical energy in question can be generated in two forms: direct current or alternating current. The generated alternating current can be stepped up or stepped down through transformers.

Power transformers play a crucial role in elevating the energy produced at power plants to enable the healthy transmission of electricity to urban centers.

Electric energy can be stepped down through low and medium voltage transformers to become suitable for consumer use.

Polarity Structure in Power Transformers

Polarity refers to the indication of how transformer windings change their ends according to the frequency of the current. These polarities make it easier to connect transformers together in series or in parallel. This ensures that the electrical transmission system is properly established.

There are different and important methods for polarities, such as:

Star-star connection

Star-delta connection

Delta-delta connection

Delta-star connection

These connection types are determined based on how the primary and secondary windings are arranged, depending on the structure of the transformer and its windings.

Areas of Use for Power Transformers

The areas of use for transformers include:

Power plants

Electric energy distribution areas

Devices that receive energy from the grid

In summary, transformers are suitable for use in places where alternating current is applied.

Power transformers are also used in areas where energy needs to be stepped up. Dams are among the places where power transformers are widely used.

The Importance of Transformer Usage

Transformers are the most important electrical machines that enable the transmission and widespread distribution of electrical energy. This allows energy to be easily transmitted over long distances from where it is generated.

To use the energy transferred to distant locations, it must be transformed into low or medium voltage.

Transformers raise the voltage to a sufficient level for efficient transmission.

In cases where the voltage is insufficient, voltage transformers are used to raise the value.

Transformers are vital for the efficient and widespread use of electrical energy in all fields.
