Electrical transformer is a device which is used mainly for transforming electrical energy. It is able to alter the voltage from high to low one. This enables the transportation of the electricity more easily and efficiently.
One of the most popular electrical transformers is power line electrical transformer. There are some other types and sizes available for you. They come in a wide rage of varieties, from huge and multi ton units which are commonly used in power plants up to intermediate units which are commonly used in electronic poles. In addition, you can also find transformer which is used for residential. This small electrical transformer is commonly used for electronic appliances and microphones.
Among all types of electrical transformers, the most common and the most needed transformer is the electricity transportation from power plants to businesses and homes. Since power commonly has to travel in a long distance, it will be transformed first to a more controllable state. Then, it will be transfer over and over. Or, it will be stepped down repeatedly when it comes closer to the final destination.
Commonly, the power leaves the plant in a high voltage. As the power reaches the substation, the voltage will be lowered. And, when it comes to a smaller transformer, the power on the top of the electric poles is stepped down. This is an endless process which will repeat till the power is in a usable level.
Furthermore, electrical transformers are commonly set on the top of the electric poles. Commonly, they have windings or coils which are wrapped around the core. The coils let the power to travel through. More coils indicate that they can handle higher voltage and fewer coils can handle lower voltage.
These devices are very useful for industry. With their higher efficiency, these devices can transfer power to a close or far distance economically and efficiently. The businesses and homes which are located in a far distance from the pole will be able to obtain affordable electricity. Electricity which is used today has passed through these devices prior to reaching the users.
