Single Phase vs. Three Phase?

Your AC Transformers FAQSingle Phase vs. Three Phase?

Single Phase vs. Three Phase?  The difference between the two is a commonly posed AC transformer question and it’s important to know what differentiates the two.  This will help you properly determine which is best suited for your power source requirements. 

The definition of a single phase transformer is basically two lines, which are comprised of a primary winding and a secondary winding.  These two windings work together to produce the necessary voltage transformation.  Most power, however, is delivered in the form of three phase power which is the most common type of electricity produced by power companies.  A three phase transformer has three rotating coils, or windings, which pass through a magnetic field to produce electricity.  This electricity is then sent out in three lines, thereby the term “three phase power.”  This answers the basic configuration differences between Single Phase vs. Three Phase.

In the Single Phase vs. Three Phase scenario, the three phaseSingle Phase vs. Three Phase? transformer's windings are spaced 120 degrees apart and must be connected in the proper sequence to match incoming voltage.  The power company voltage is then transformed to the proper polarity and phasing needed for consumption by the general public.  Large industrial loads are more efficiently served by three phase voltage over single phase voltage.  Single phase power is available as two phases in a three phase system, or sometimes, between one phase and ground.
