The Perks of Three-Phase Generators

The Perks of Three-Phase Generators

Posted in: Diesel Generators Engine & Drivetrain Performance

There are single-phase and three-phase generators, but not a lot of people understand the difference between the two.  The three-phase generator is most often used in large equipment, while everyday household equipment generally uses single-phase generators. The difference between the two types of generators involves an understanding of the science behind electric currents.

When operating a single-phase generator, you are working with a single wave of power. In the single-phase operation, the electric power will fall to zero three times each cycle. In a three-phase generator, power will never drop to zero because the circuit provides three alternating currents. The currents are of equal frequency, but they are 120 degrees out of phase with each other, making the waves of power constant.

A three-phase system requires less copper or aluminum to generate the same level of power compared to a single-phase generator. A three-phase generator is fed using three phases to ensure a better power supply. At the top of the three-phase generators, three power wires are supplied with the use of four wires. The three wires are called RST, and the other one is neutral.

In a situation that requires continuous power, three-phase generators are a requirement. This generator supplies power to devices that use three-phase voltage. It is also the system needed to supply electricity to remote places that need an energy-efficient solution. 

The advantages of the three-phase generator include:

  • Greater efficiency in providing electric supply to various applications around the world.
  • More constant torque and fewer vibrations.
  • Uninterrupted availability of instantaneous power.
  • The total power of a three-phase generator is never zero.

If you are looking for continuity of electric supply without supply failure, a three-phase generator is the best option.
