	What is a Step Down Transformer? Devices that are used to step down electrical current at input power sources, which allows voltage to be compatible with equipment.
	Voltage Transformers Transformers that are designed for specific applications that need specified electrical voltage.
	Step Up Transformers A transformer that has the secondary winding higher than the primary allowing the transformer to increase input voltage.
	Power Transformers Devices that convert the incoming line voltage to a higher or lower electrical current to match voltage of equipment.
	Three Phase Transformers Transformers that are used throughout industry to change values of three phase voltage and current.
	Isolation Transformers Transformers that transfer energy from the alternating current supply to an electrical load.  They prevent certain types of harmonics.
	Buck Boost Transformers Buck Boost devices are used to make small adjustments to incoming voltages such as lighting applications.
	Phase Converters Devices that convert single phase power into three phase power.
	Acme Transformers Acme Transformers is an industrial leader offering superior service, quality products and technical service.
	Ace Phase Converters Ace Phase Converter has been in business for 25 years and their professional and experienced engineering staff can assist you with your phase converter application requirements.

Three Phase

Transformers
 

Three phase transformers were designed because three phase electricity is used for power distribution systems to step up or step down voltage.  A single phase transformer's configurations could be used in these applications.  However, three phase transformers are able to perform better with less material requirements, less size, and less weight than the single phase transformers.

A three phase transformer is constructed by placing three single phase transformers on a single core. They are then put in an enclosure, which is filled with dielectric oil.  This oil is a nonconductor of electricity, and it provides electrical insulation between the windings and the case.  It also provides cooling and prevents moisture from forming, which can deteriorate the winding insulation.

The main benefits of using three phase transformers are that all three wires can carry the same current.  Secondary, they provide a balanced and linear load.  If you do not have a balanced load, it can result in damaged motors and equipment by causing over heating.  A great resource for all your three phase transformers is TEMCo Three Phase Transformers.  They offer quality, energy efficient three phase transformers.

Three phase transformers have four possible connection combinations:

• Delta to Delta - for use in industrial applications

• Delta to Wye - for use in industrial and commercial applications

• Wye to Delta - used for high voltage transmissions

• Wye to Wye - used very rarely, because it causes harmonics and does not provide a balanced load

Always remember, when purchasing a three phase transformer, seek out a more reputable and experienced manufacturer such as  Acme Step Down Transformers . A quality manufacturer will save you money in the long run and will provide you many years of quality service.

Step Down Transformers come in sizes as small as thumb nails to as large as big power grid units.
