Transformers generally have one of two types of cores: Core Type and Shell Type. These two types are distinguished from each other by the manner in which the primary and secondary coils are place around the steel core.

The different types of transformer are step up and step down transformer, power transformer, distribution transformer, instrument transformer, single phase and three phase transformer, auto transformer, etc.
There are two general types of transformer construction: core-type and shell-type. Single-phase core-type construction consists of a core that provides a single-path magnetic circuit.
Transformers are most commonly used for increasing low AC voltages at high current (a step-up transformer) or decreasing high AC voltages at low current (a step-down transformer) in electric power applications, and for coupling the stages of signal-processing circuits.
A transformer operates on the principle of electromagnetic induction. It has a magnetic core over which two sets of windings, termed as primary and secondary, are suitably placed. When one of the windings is connected to an AC supply, an emf is induced on the other winding which is proportional to the number of turns.
Depending upon the type of construction used, the transformers are classified into two categories viz.: (i) Core type, and (ii) Shell type. Depending upon the type of service, in the field of power system, they are classified as: (i) Power transformers, and (ii) Distribution transformers.
In distribution networks, the step-down transformer is commonly used to convert the high grid voltage to low voltage that can be used for home appliances.

Definition: The transformer which is free from all types of losses is known as an ideal transformer. It is an imaginary transformer that has no core loss, no ohmic resistance, and no leakage flux.
Leave a Comment / Transformer. An ideal transformer is one which has no losses (no iron loss and no copper loss) and no leakage flux i.e. all the flux produced by the primary winding is linking with the secondary winding.
What are the main applications of Transformers?
Transformers are most commonly used for increasing low AC voltages at high current (a step-up transformer) or decreasing high AC voltages at low current (a step-down transformer) in electric power applications, and for coupling the stages of signal-processing circuits.
What is main use of transformer?
Transformers are employed for widely varying purposes; e.g., to reduce the voltage of conventional power circuits to operate low-voltage devices, such as doorbells and toy electric trains, and to raise the voltage from electric generators so that electric power can be transmitted over long distances.
