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

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

• They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.

• The primary winding is connected to the input voltage source, while the...read more

Transformer parts are essential components that help in the functioning of a transformer.

• The core is the central part of a transformer that is made of laminated sheets of iron or steel.

• The windings are the coils of wire that are wrapped around the core and carry the electrical current.

• The insulation is used to separate the windings and prevent electrical arcing.

• The tap changer is a device that allows for the adjustment...read more
