Introduction about 3 Phase Transformer

3 Phase Transformer is used to adjust 3 phase incoming power to a more desirable 3 phase outgoing power. In power distribution systems a 3 phase transformer transforms power to very high voltages in a 3 phase configuration in order to eliminate as much power loss as possible while it is transmitted over long distances. The higher the voltage and the smaller the amperage; the less loss resulting from resistance is encountered. The size of the 3 phase transformer lines can be smaller, as a result. 3 phase power is produced in most energy production systems by virtue of the fact that these systems use generators which have three evenly spaced coils passing through a magnetic field. Each of these coils represents one leg of a 3 phase system, thus the name 3 phase transformer

Since most power is transmitted as 3 phase AC, a 3 phase transformer is used to accept the power from the generators and step it up as a very high voltage current carried over three individual high power lines. The three lines allow this system to carry 173% more power than a 2-line single phase system.

There may be several 3 phase transformers along the route, adjusting the 3 phase power to ever lower voltages until at last either ending where single stage circuits are split off, or where there is use of 3 phase power applications.

Large motors, large computer installations, air conditioning and heating installations, CNC mills, all often use 3 phase transformer power to great advantage. Motors run smoother, cooler and more efficiently. In many instances 3 phase transformer power is also cheaper. Motors that are 3 phase can be smaller and yet more efficient and powerful than single phase motors.
