GRUPELquality, reliability and efficiency



    The single-phase generators range consists of several very reliable machines that work in a system powered by single-phase voltage. Their power ranges the usual single-phase installations commonly known to be 5 to 20 kilowatts .



    This is the most popular and versatile range of generators. They are designed for a three-phase electrical network, but in some cases, when there is a three-phase mains and single-phase consumers, their use is extremely appropriate.



    The range of industrial generators covers capacities in range 500 to 2500 kilowatts. Industrial diesel generators are specially developed for industrial needs with high energy requirements.

Generators: The Powerful Engine of Energy

In today’s world, where electricity is vital to virtually every aspect of our lives, diesel generators occupy a central place in the field of electric power. These powerful devices provide a reliable solution for providing electricity in a variety of settings, from domestic needs to industrial applications and natural disasters. In this extensive article, we will explore diesel generators in depth – their functioning, applications, advantages and disadvantages.

What is a diesel generator?

Diesel generators are a combination of an internal combustion engine and a generator used to produce electricity. These systems work by converting chemical energy contained in the fuel into mechanical energy, which is then transformed into electrical energy by the generator. Diesel generators are characterized by high efficiency and durability, which makes them a preferred choice in many fields.

How does a diesel generator work?

The main part of the diesel generator is the internal combustion engine, which uses diesel as fuel. The process of diesel combustion creates internal pressure in the engine cylinder, as a result of which the Porsche moves. This reciprocating moving mechanism is connected to the generator, which converts mechanical energy into electrical energy by using the principle of the electromagnetic induction field.


The generator contains a rotating magnetic rotor immersed in an electromagnetic field that generates an electric current in the stator (winding of wires) as the rotor rotates. This process creates alternating current (AC), which is often converted to direct current (DC) through the use of current-regulating devices, and it becomes ready for use.

Applications of diesel generators

  • In houses and business buildings
  • Diesel generators are used in private homes and business buildings as the main or backup source of electricity. They ensure power continuity, especially during power outages or failures, which is critical for keeping home appliances and business equipment running.

In industry

In industry, diesel generators are used to provide power for large manufacturing plants, industrial complexes and other industrial environments where power continuity is essential.

In the construction and mining industry

Diesel generators are widely used in the construction and mining industries as a source of power for temporary buildings, drilling rigs, construction machinery and other equipment that cannot be connected to a large power grid.

For emergencies and disasters

Diesel generators are essential during natural disasters, such as storms, floods or earthquakes, when mains power may be disrupted. These generators provide essential electricity for emergency services, hospitals, rescue teams and for public buildings.
