How Three Phase Transformers Works

Three phase transformers are used primarily in electrical power transmission.  Three phase electric power is a type of polyphase system mainly used to power motors and many other devices.  A three-phase system uses less conductor material to transmit electric power than single-phase power.  A three phase transformer is used throughout the industry to change values of three phase voltage and current.  Since three phase power is the most common way in which power is produced, transmitted, and used, an understanding of how three phase transformer connections are made is essential. Three phase transformers have several advantages over bundling single phase transformers together for applications.  Three phase transformer use less material and therefore weight less and are generally smaller, and they increase reliability.

There are four different connections and they are:

  1. Delta to Delta

  2. Delta to Wye

  3. Wye to Delta

  4. Wye to Wye

The Delta to Delta three phase transformer are used in short distance distribution.  It is used in industrial applications and neighborhoods and small commercial loads close to the substation.  In a delta system only one voltage is available between any two wires.  It is illustrated by a simple triangle.  A wire from each point to the triangle would represent a three-phase, three-wire delta system.  The voltage is the same between any two wires.

Three Phase Transformer Delta to Delta Connection

Delta to Delta Three Phase Transformer Connection

In a wye three phase transformer the voltage between any two wires will always give the same amount of voltage on a three phase system.  However, the voltage between any one of the phase conductors and the neutral will be less than the power conductors.  Let's take, for example, if the voltage of any of the two phases of a three wire system is 208v, then the voltage from any phase conductor to ground will be 120v.  This is due to the square root of three phase power.  A wye to wye connections are used rarely because of its balancing problems and it can cause harmonics problem.

Three Phase Tansformer Wye Connection

Wye-Wye Three Phase Transformer Connection

Three phase transformers that have a delta-wye have it primary winding connected in delta and its secondary winding connected in a wye.  This connection is the most common and is used in commercial and industrial applications.  A wye-delta three phase transformer has its primary winding connected in a wye and its secondary winding connected in a delta as is illustrated below.  This connection on a three phase transformer is used in high voltage transmission's
