What are three-phase generators and how do they work?

Three-phase electric power is one of the most common methods through which current electric power generation, transmission, and distribution is alternated. It can be considered a type of polyphase system which is often used by electrical grids worldwide to transfer power.

It is also commonly used to power large motors and other heavy loads. Three-wire, three-phase circuits are considered more economically efficient than the equivalent two-wire, single-phase circuits at the same line to ground voltage.

The reason for this is as these three-wire, three-phase circuits utilise far less conductor material to transmit a given amount of electrical power. The invention of polyphase power systems in the late 1880s can be attributed to:

  • Galileo Ferraris
  • Mikhail Dolivo-Dobrovolsky
  • Jonas Wenström
  • John Hopkinson
  • Nikola Tesla

Applications

Three-phase generators are ideal for industrial uses as result of high constant power which is required to run industrial units. These generators are especially used in the following areas:

  • Data centres
  • Motors
  • Industrial plants and factories
  • Agriculture
  • Mining and construction sites, and more.

Common features and advantages

Soe typical features of an AC Three-phase generator includes, but is not limited to:

  • They are powerful devices with a typical output voltage of 480V.
  • They are flexible in stepping up or down using transformers.
  • They offer transmission advantages with thinner transmission links
  • They hold an advantage over single-phase generators by being smaller, weighing less, and costing less for the generation of the same amount of power.
  • They perform well with hardly any issues pertaining to upkeep and maintenance.

Additional advantages include:

  • Three-phase generators are more effective in energy supply and it is one of the most used generators worldwide.
  • The torque on these generators is constant, suffering less vibrations, with the total instantaneous power also being constant.
  • The windings of a three-phase generator is used more efficiently.

Why are CAT Generators so popular?

CAT generators are ranked as one of the best generators in the industries and they have numerous applications across industries. The reasons why they are considered the best, amidst the other top-quality generators can be attributed to:

  • They last for a lengthy period if they are maintained and used for the right purposes.
  • They may be pricey, but they are worth the top-notch quality received.
  • They are some of the most accessible and widely available generators in the world.

Comparison between single-phase and three-phase systems

Single-Phase Three-Phase
Power flows through one conductor Power flows through three conductors
Requires two wires to complete the circuit (one phase and one neutral) Requires three phase wires along with one neutral wire to complete the circuit
Up to 240V Up to 415V
Operates in only one phase which may result in a power drop if a fault occurs in the network Operates in three phases, should a fault occur in one, the others will still supply power
Less efficient More efficient
Ideal for house appliances or devices Ideal for larger load applications such as industrial uses
Requires more maintenance if the power supply fails completely Can avoid down-time which means cost-savings on maintenance and avoids loss of operations
Pulsating torque Uniform torque
Parallel operation is complex Parallel operation is simplified

What to consider when buying a generator

One of the items which must be at the top of the list of considerations revolves around the capacity of the generator. The voltage rating as well as the number of phases must be considered. The generator must provide power at the correct voltage in addition to the number of phases which are required by the equipment to be powered.

However, if it is for business and industrial use where large machinery and equipment will require power for short or extended periods, a much larger generator that produces more power will be more suited.

Another important consideration is the fuel that the generator will use between petrol, diesel, LP gas, or natural gas. The duty and the operation of the generator must be considered regarding whether it is just for standby or for prime duty. The location of the generator must be considered regarding whether it will be kept indoors or outdoors.

Finally, the noise that is produced and the costs along with other economic considerations such as maintenance, permits, and others, must be considered.
