Voltage Transformers

You must be getting very familiar with transformers by now if you have been reading all the articles and clicking onto informational sites.

Single-phase transformers certainly have their place in the solution of voltage control.  Most of the time, single-phase transformers are used in rural areas where three-phase power isn’t available or is just too expensive trying to obtain it from the power companies.

Residential areas and small businesses in North America usually utilize single-phase transformers (120 volts to 240 volts) because they don’t usually require three-phase power loads, and often, a single-phase transformer will be assigned to each customer individually.  They are used in systems in which all voltages of the power supply vary in unison.  Most applications include appliances, lighting and heating systems, and equipment with motors that don’t require high voltage levels or need varied electrical frequency loads.

Can Single-Phase Transformers Produce Three-Phase Power?

In rural areas, some farmers and businesses may need three-phase power, and they will usually use a phase converter, which can convert three-phase electricity from a single-phase power source.  Single-phase transformers can’t convert single-phase power to three-phase power.  They are used to control voltage usually stepping up or stepping down voltage to required power loads from a specific power input source.  Businesses needing three-phase power usually have larger equipment designed to operate with three-phase electricity.

Applications for Single-Phase Power Transformers

Single phase voltage transformers offer excellent capabilities for auto transformers, industrial controls, isolation, low voltage, step up, and step down applications. They are also used extensively for lighting and heating applications. Single phase transformers may be used in conjunction with three-phase transformers, but they don’t handle large power loads as effectively as their three-phase counterparts.

When three-phase voltage is needed, single-phase transformers can be banked together by using three transformers joined to form one unit to operate as a three-phase transformer.  However, when needed, it is better to use a three-phase transformer because they have less conductor materials and are smaller in size.  Single-phase transformers are not the best choice in controlling voltage for three-phase electricity.  There would be more chance for repair, and they use more conductor materials and are bigger in size.
