A piece of equipment called an electric transformer or power transformer is made to adjust the magnitude of AC voltage in a circuit while maintaining frequency and doing so with the least amount of power loss possible. Voltages may be stepped up and down using it. Electromagnetic induction is used to transfer power from the input side to the output side.

It is utilized to effectively transport electricity produced at a remote point to the customer at the necessary voltage. Transformers come in a range of sizes and grades, from the enormous ones used in substations to the minuscule ones found on electronic boards.

An Ideal transformer

A primary winding and a secondary winding are wrapped around the two vertical limbs of the core to create the perfect transformer. An alternating magnetic field and therefore an alternating magnetic flux is created when an alternating voltage is given to the transformer's primary winding. The number of coil turns determines how much magnetic field is generated. The secondary coil experiences an EMF due to this magnetic flux. It is possible to link the load to the secondary winding ...
... that allows current to flow.

• Step-up Transformer

The secondary winding in step-up transformers has more turns than the primary winding. Additionally, the secondary voltage must be greater than the primary voltage. To boost transmission voltage and decrease transmission losses, step-up transformers are utilized. They are referred to as power transformers and can be found in generating plants.

• Step-Down Transformer

The voltage of a step-down transformer is determined by the difference between the number of turns on the secondary side and the number of windings on the primary side. On the distribution side of the electrical system, these transformers from electric transformer manufacturer are utilized to lower voltage.

Electric transformer losses

Transformer losses may be divided into two categories: winding loss and core loss. Because of the conductor's resistance, winding loss happens. The square of the stream passing through it determines its proportion. Thick copper conductors are used to cutting down on winding loss and minimize current flow resistance.

Eddy currents that occur in the transformer core and the hysteresis effect are the causes of core losses. Iron losses, usually referred to as core losses, are independent of load and are constantly constant. Core losses can be decreased and transformer efficiency can be increased by using thick conductors and a laminated soft iron core.

Electric transformers are employed in the electricity grid for what reasons?

A power transmission and distribution network's most crucial element might be considered to be an electric transformer. It fulfills the responsibility of increasing transmission efficiency, lower losses and lowering transmission costs. Power is produced in power plants at voltages between 11 and 28 kV and 50 Hz. The voltage is increased to 220 kV or higher and then transferred to lower transmission losses.

It is again stepped down to 33 kV or 11 kV at the distribution substation, depending on the need, and fed to industries. At the home consumer end, it is once more stepped down to the user's low voltage loads. You can buy transformers from a reliable electric transformer supplier.
