The working principle of a transformer involves the transfer of energy from one conductor to another, and this transmission process is facilitated by a magnetic flux. A transformer, consisting of two coils and a core, begins operating when voltage is applied to one of the coils wound around the core. As a result of this voltage, a magnetic flux is created, leading to the induction of voltage in the output coil.

What Is a Transformer?
Commonly known as a “trafo,” a transformer is a machine that facilitates the transmission of electrical energy. It is used in various applications wherever there is a need for electricity, including city power grids. Different types of transformers have been developed depending on the application and requirements of the specific area. These transformer types include:
- Dry Type
- Special Type

Trans-El Transformer stands out among leading companies in the industry by manufacturing transformer types that conform to international quality standards, tailored to meet specific needs.
Characteristics of Transformers
The primary characteristics of transformers that take on the role of energy transmission are:
- They transfer energy from one electrical circuit to another through an electromagnetic field.
- They modify the current’s intensity, voltage, and shape as needed.
- Different types exist, such as insulation, power, and current sensing transformers.
Transformers Based on Purpose
Transformers are categorized based on their intended purposes:
- Auto Transformer
- Isolation Transformer
- Step-Down Transformer
- Step-Up Transformer
- Measurement Transformers
This type of transformer offers high efficiency with smaller dimensions. It has only one winding that serves as both primary and secondary.
Used to isolate two circuits from each other, its purpose is not voltage transformation.
Commonly used for devices like battery chargers and vacuum cleaners, the secondary winding voltage is lower than the primary winding. In other words, the output voltage signal is lower than the input voltage signal.
Unlike step-down transformers, the secondary winding voltage is higher than the primary winding in step-up transformers. They are used in devices like televisions.
Used in places where voltage and current levels are high, they reduce voltage and current values in the secondary windings to levels suitable for measurement devices. They come in two types: current transformers and voltage transformers.
