A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are commonly used to step up or step down voltage in electrical power distribution systems.

• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of ferromagnetic material.

• The primary coil is connected to the input voltage sou...read more

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers work on the principle of electromagnetic induction

• They have two coils - primary and secondary, which are magnetically coupled

• The primary coil is connected to a source of alternating current, creating a changing magnetic field

• This changing magnetic field induces a voltage in the secondar...read more

Transformer windings can be classified as concentric or sandwich windings.

• Concentric windings have all the windings placed on the same limb of the core.

• Sandwich windings have windings placed on different limbs of the core.

• Concentric windings are easier to manufacture and have better cooling.

• Sandwich windings are more compact and have better short-circuit strength.

• Examples: Concentric winding - distribution transformers

The most important points during winding include tension control, proper alignment, and consistent winding patterns.

• Maintaining proper tension control to prevent breakage or stretching of the material

• Ensuring proper alignment of the material on the winding equipment to avoid uneven winding

• Following consistent winding patterns to create uniform and neat rolls of material
