Single phase transformers are power transformers that use single-phase alternating current. They operate on Ohm’s Law, and outside of a minor power loss because of heat, do not remove or create power.
How Do These Transformers Work?
Single phase transformers rely on both a primary and secondary coiling in order to conduct electrical power through a magnetic field. The primary coiling normally takes the electrical power, while the secondary coiling normally delivers the power that is needed. Both of these coilings are wrapped around a magnetic iron circuit that is commonly referred to as the core.
Uses
Single phase transformers can be used for both commercial and residential purposes. The highest amount of voltage it can deliver is controlled by industry regulations and infrastructure. Even with regulation, at such levels, these transformers are capable of producing enough energy to power many businesses’ lighting and equipment. Lower voltage outputs delivered by this type of transformer can be used to power many everyday appliances and electronics, including computers.
Benefits
The benefits of single phase transformers include the fact that they can boost or reduce the amount of voltage of electricity without changing the amount of electricity that is transferred through the magnetic circuit. This makes this type of transformer very useful for transferring electricity to many different types of establishments, including both commercial and residential.
In fact, single phase transformers are preferred to three phase transformers in rural areas because a three phase costs much higher, plus it is capable of generating much more electricity than most rural areas need based on lower population and fewer commercial entities located in these areas. Three phase transformers are often used in cities where the power requirements are greater because of larger populations and more commercial entities being present here.
