Electrical Transformers

Transformers, Induction

A transformer is an electrical device that uses electromagnetic induction to transfer electricity between two or more electrical circuits. An alternating current flows in one coil of the transformer, producing an alternating magnetic field that induces an alternating electromotive force (or voltage) in the second coil. Thus, no metallic connection is needed between the two coils to transfer current, since the magnetic field created is used to transfer electricity. The electric current created by the movement of magnets in a magnetic field is called induced current.

Distribution and application

Transformers find application in many areas, as they allow efficient transmission and conversion of voltage. They not only help maintain the smooth operation of various electrical devices in the system by protecting them from voltage peaks and drops, but also play the role of a fuse or fuse in case of current surges, short circuits, system overloads or other adverse conditions that can damage electrical devices.

• Electricity Transmission and Distribution - Transformers are used in power grids to convert high voltage to low voltage, suitable for household use, lighting, automotive electrical systems, caravans, trucks.
• Electronic Devices and Power Supplies - In electronics and home appliances, transformers lower the voltage to make it safe for low voltage appliances.
• Industrial Applications - In plants and factories, where specific voltages are required for various machines, transformers regulate the voltage to maintain safe and optimal operating conditions for the equipment.

Types of Transformers

Transformers are an important part of the energy, industry and electronics industries, as they provide flexibility and security in the transmission of energy and the supply of various types of devices.

• Wide range of toroidal transformers;
• W-shaped step-down transformers;
• PL-shaped step-down transformers;
• Toroidal transformers - donut-shaped, round;

 

• Current transformers - measuring high current values;
• Audio transformers for amplifying, clearing interference from audio signals;
• Autotransformers - automatic, adjustable transformers that maintain electricity in range;

 

• Three-phase transformers
• Single-phase transformers
