Many people wonder, what is phase 3 electricity? It is the supply of electricity to a building not just from one source, but from two or three sources. As you can imagine, this means that the electricity can be supplied from any direction. This is called a three phase supply. The main benefit of this is the ability to use more power for large buildings with heavy demand. This is not normally used for small homes or offices, but is usually reserved for larger commercial applications such as factories and warehouses.
The main advantage of having a three phase system as opposed to a single phase system is that it allows for increased power over long distances. It also allows for smaller sized wires because less current flows through them at once than in a single phase supply.
The three-phase system was developed to allow for a more efficient use of conductor material. In a single phase power system, either alternating current (AC) or direct current (DC) is used. A single phase AC system uses a single source of voltage that alternates in polarity at a fixed frequency. A DC system delivers a constant polarity and voltage level.
A three-phase system uses three sources of voltage that are 120 degrees apart in time, creating a constant supply of power at any given time. The key advantage to this type of system is the elimination of zero crossings (when the magnitude and polarity of the voltage are equal to zero). This allows for better efficiency when applying transformers and other types of equipment to distribute electrical power.
A useful example of phase three electricity is in electric motors. Electric motors are a common piece of equipment in many industries. Such equipment needs to have a good level of reliability, so that businesses can be confident that they will work when needed.
If a motor is used for a long time, it can create high levels of heat which can affect its performance and reliability. This means that the motor can take longer to start when required, and may also reduce its life span.
Phase three electricity is a good solution for this issue because it allows the motor to use variable frequency drive (VFD) technology to produce more torque from less current and therefore reduce heat build up.
Phase three electricity comes from an electrical generator, which uses an alternating current (AC) to produce energy which then powers the motor. The generator works by producing an electromagnetic field which pushes the electrons along the wires in an alternating pattern and creates voltage in them.
