3 Phase Transformer

3 phase transformers are the most common type of transformers used in our power distribution system and also in industrial applications.  These transformers are used throughout the world to change three phase voltage and current.  The reason 3 phase transformers are used instead of 1 phase transformers is they are more efficient, they are able to perform with less material, meaning they are smaller in size and weight than their counterpart the single phase transformer.  TEMCo offers a large selection of 3 phase transformers.  With only  quality parts and design, TEMCo 3 phase transformer is one of the most efficient transformers on the market.  TEMCo offers quality 3 phase transformers at wholesale prices, meaning we guaranteed the lowest price on your 3 phase transformer.  3 phase transformer are usually a step up transformer or a step down transformer but in many cases are offered with different features such as isolation.

3 Phase Transformer Construction  

A 3 phase transformer is design with three sets of primary and secondary windings, and wound around one leg of an iron core assembly.  Essentially it looks like three single phase transformer sharing a joined core the figure below shows this:

Three Phase Transformer core

On a 3 phase transformer, the primary and secondary winding will be connected in either a Wye or Delta configuration or a combination of the two to form a complete unit.  3 phase transformers are put in enclosure and can be filled with an dielectric oil which is called a oil filled transformer or can be constructed in a dry type transformer form. 

3 Phase Transformer Configurations

The utility company generators produce electricity by rotating 3 coils or windings through a magnetic field with the generator.  The coils or winding are space 120 degrees apart.  When rotating through the magnetic field they generate power and then sent out on three lines as in three-phase power. The  3 phase transformer must have the winding connected in the proper sequence to produce the correct voltage and to maintain the proper phasing or polarity.  A 3 phase transformer is used in the beginning of the power distribution to step up the electricity to be carried on transmission lines and then step down to the correct voltage for our homes and businesses. 

Determining the Correct Size of a 3 Phase Transformer

To determine the correct size of a 3 phase transformer you will need three items.

  1. Load voltage

  2. Load Current/Amps

  3. Line Voltage

Below you will find the formula for determining single phase transformers and 3-phase transformers.  An important fact to remember the KVA of the transformer should be equal or greater than the KVA of the load to handle requirements and future expansion.  TEMCo  team of specialist can help you determine the correct size and type of 3 phase transformer you will require for your application.  With over 40 years of experience and TEMCo dedication to their customer you can rest assured you are getting the correct  phase transformer for your application the first time.

 

Transformer Selection Formulas

3 Phase Transformer Connections

There are 4 possible transformer connection combinations and which one you used is based on your application.  A Wye connection provides the opportunity for multiple voltages, while the Delta connections have a higher level of reliability.  For example, in a delta connection if one winding would fail, the other two can still maintain full line voltages to the load.  

The Combinations are:

Delta to Wye:   is the most common and used in commercial and industrial applications.
Delta to Delta:  used in some industrial applications.
Wye to Delta:  used in high voltage transmission applications.
Wye to Wye:  this combination is used rarely because causes harmonics and balancing problems.
