Structure of a transformer A basic transformer is made from two coils of wire; a primary coil from the ac input and a secondary coil leading to the ac output. The coils are not electrically connected. Instead, they are wound around an iron core..
How a transformer is constructed?
In all types of transformers, core is constructed by assembling (stacking) laminated sheets of steel, with minimum air-gap between them (to achieve continuous magnetic path). The steel used is having high silicon content and sometimes heat treated, to provide high permeability and low hysteresis loss..
How is a current transformer constructed?
Current transformers typically consist of a silicon steel ring core wound with many turns of copper wire, as shown in the illustration to the right. The conductor carrying the primary current is passed through the ring. The CT's primary, therefore, consists of a single 'turn'..

Transformer parts
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. Each leg of the core has overlapped high and low voltage windings..
Types of transformer
Different parts of an electrical transformer are made of different materials. Windings are usually made of copper or aluminum, while the laminations are made of steel, often silicon steel. Cores can also be made of iron, amorphous metals, and ferrite ceramics, among others..

What is the construction of a control transformer?
Control transformers with two primary coils and one secondary coil are the most common. A control transformer's primary coils are crossed so that metal links can be used to connect the primaries for 240 V or 480 V operation (see Figure 1)..
What is the construction of current transformer?
A window current transformer is a transformer that consists of a secondary winding wrapped around a core and the primary sent through the opening in the core. After the secondary is wound around the core, the assembly is placed into a mold, and an insulating material is injected around the transformer..
Basically a transformer consists of two inductive coils; primary winding and secondary winding. The coils are electrically separated but magnetically linked to each other. When, primary winding is connected to a source of alternating voltage, alternating magnetic flux is produced around the winding.
The construction of transformer is of iron core laminated with steel bands. Core laminations are constructed from insulated metal thin metal strips. These laminations are separated and wound around the limb using a sheet of coat or parchment. The winding consists of two types, main and secondary winding.
Construction of transformer
Transformer used to scale alternating current, used as sensor for AC power
A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary.
A distribution transformer or service transformer is a transformer that provides the
Final stage in power distribution to users
A distribution transformer or service transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer. The invention of a practical efficient transformer made AC power distribution feasible; a system using distribution transformers was demonstrated as early as 1882.
A flyback transformer (FBT)
High frequency pulse transformer, commonly used to drive cathode ray tubes
A flyback transformer (FBT), also called a line output transformer (LOPT), is a special type of electrical transformer. It was initially designed to generate high-voltage sawtooth signals at a relatively high frequency. In modern applications, it is used extensively in switched-mode power supplies for both low (3 V) and high voltage supplies.
High-voltage transformer fire barriers
High-voltage transformer fire barriers, also known as transformer firewalls, transformer ballistic firewalls, or transformer blast walls, are outdoor countermeasures against a fire or exposion involving a single transformer from damaging adjacent transformers. These barriers compartmentalize transformer fires and explosions involving combustible transformer oil.
A padmount or pad-mounted transformer is a
Ground mounted transformer
A padmount or pad-mounted transformer is a ground-mounted electric power distribution transformer in a locked steel cabinet mounted on a concrete pad. Since all energized connection points are securely enclosed in a grounded metal housing, a padmount transformer can be installed in places that do not have room for a fenced enclosure. Padmount transformers are used with underground electric power distribution lines at service drops to step down the primary voltage on the line to the lower secondary voltage supplied to utility customers. A single transformer may serve one large building or many homes.
Rotary transformer
A rotary (rotatory) transformer is a specialized transformer used to couple electrical signals between two parts that rotate in relation to each other. They may be either cylindrical or 'pancake' shaped.
Type of electrical transformer
A rotary variable differential transformer (RVDT) is a type of electrical transformer used for measuring angular displacement. The transformer has a rotor which can be turned by an external force. The transformer acts as an electromechanical transducer that outputs an alternating current (AC) voltage proportional to the angular displacement of its rotor shaft.
A transformer is a passive component that transfers electrical energy from
Device to couple energy between circuits
A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil.
American film series
Transformers is a series of science fiction action films based on the Transformers franchise of the 1980s. Michael Bay directed the first five live action films: Transformers (2007), Revenge of the Fallen (2009), Dark of the Moon (2011), Age of Extinction (2014), and The Last Knight (2017), and has served as a producer for subsequent films. A sixth film Bumblebee, directed by Travis Knight, was released in 2018, while a seventh film, Rise of the Beasts, directed by Steven Caple Jr. was released in 2023.
