Transformer is a static electrical device that transfers electric energy between two circuits by using the principle of electromagnetic induction. It can increase or decrease AC voltage as required. It consists of a magnetic core and two separate windings, the primary and the secondary.
The primary winding is connected to a live source of AC power. The resulting magnetic flux induces an EMF in the secondary winding.

Parts

They can step up or down voltage levels to match specific requirements. They are also crucial for transmitting currents over long distances.
There are many types of transformers, but they all have the same essential parts. The core of a transformer is a cylindrical or square piece of iron. It is wrapped with insulating sheets to prevent heat transfer from one side to the other.
The core is the heart of a transformer, and its job is to convert magnetic flux into electricity. A transformer needs to be made of good quality steel so that it can handle high levels of current and temperatures. The insulating sheet is usually made of silicon steel and has an insulated paint on it to minimize the loss of energy due to heat.
As you can see, the different parts of a transformer are crucial for understanding how it works. Make sure you know all these details before preparing for the AE/JE exam. To help you prepare for the upcoming AE/JE exams, we have created a series of e-books and online practice tests. These mock tests will allow you to get familiar with the format and type of questions asked in the AE/JE exam.

Symbols
There are a number of different types of transformers used in electrical applications. Each type is designed with specific electrical characteristics to suit a particular installation or circuit needs. Most of these variations are simply a change in the construction or shape of the transformer core, while others may be customized to handle higher voltages or currents.
In general, the primary symbol for a transformer is two parallel lines. One line represents the primary winding, and the other represents the secondary. The lines are magnetically coupled, so the two sides of the transformer share a common magnetic field. The effect is the transformation of electricity from higher to lower voltages.
The polarity of the input current and the output current are shown with the appropriate symbols in the diagram. In most cases, the output current is a function of the input current. It is also possible to have a variable output current, which allows the transformer to respond to changing load demands.
Another important consideration when using a transformer is the amount of heat it generates. This can be a problem if not correctly cooled since excess heat can damage the transformer and create dangerous situations. To avoid this, the transformer must be adequately insulated. The insulation is usually made of polyurethane or epoxy resin.
Function
A transformer is a device that converts voltage levels from one to another. It also reduces currents and changes the direction of current flow. This is mainly done by changing the magnetic field of the conductive core. It is used to regulate the output voltage of a generator. It can be either a step-up or a step-down transformer. A transformer can also be used to connect an unbalanced load. It is a handy and versatile device that is used in almost all industries.
The primary function of a transformer is to transform high voltage into low voltage. This is achieved by connecting its primary and secondary winding in a delta or star configuration. It is possible to achieve a higher or lower voltage by varying the number of turns in the primary and secondary windings. Depending on the type of connection, the transformer can also be used in a star-delta or delta-star configuration.
AC or DC can power a transformer. AC power is usually used to operate electrical devices, such as lights and appliances. It is also used in industrial applications, such as electric motors and heating systems. However, DC power is not suitable for these applications because it has a higher risk of fires and explosions. Besides, it is more expensive than AC power.
