A transformer is a basic component used in many different types of electrical systems, devices, and equipment. Choosing the right type and size of transformer to meet the needs of the given application is the first step.
In many types of applications, an off the shelf option in single phase transformers offers the lowest possible price per transformer. However, this also means that the transformer comes with standard designs and features, which may limit how it can be used in a system. For maximum flexibility or for unique equipment or system designs, custom made single phase transformers may be the best option.
Stepping Up or Down Ability
A single phase transformer is typically used to step up or step down the voltage through a system. While both are possible, it is most often the case that the single phase transformer is used to step down the voltage that comes in on the primary winding.
Through the transformer, the voltage and current on the secondary winding are adjusted up or down accordingly to meet the needs of the system, electronic device, or the application.
Efficiency of the Transformer
The choice of the type of material for the core, the material used to create the primary and secondary windings and even the design of the windings are all critical to how efficiently single phase transformers do their job. It is not uncommon for a well-designed transformer to operate at or above 95% efficiency. Some of the precision manufacturers of custom transformers routinely achieve efficiency ratings of 98-99%.
The majority of transformers that are single phase are a dry-type of isolation transformer. They can be designed to meet the requirements of the system, including specialized voltage requirements, the choice of the location of taps on the windings as well as the need for specialized terminations for the specific equipment, device or system.
