A transformer is actually an electric power source whose main function is to change the level of voltage from a certain level to another level, as needed. Power transformers of large size are used in power stations, heavy industrial plants and also in power plants. In the vast majority of cases the transformer will consist of two sets of insulated wires, with the transformer wound around the iron core. After that, an electric force is applied to one of those coils – which is called the “main coil”, an electric force which is then transmitted directly to the secondary coil magnetically. Also, it is important to note that it is a magnetic coupling of electricity that takes place without direct electrical contact, which gives the transformers the possibility to change the voltage and isolate the two electrical circuits completely from each other. In order to put the matter in order for you, we have compiled for you in the following article everything you wanted to know about transformers and their areas of responsibility in the industry.
How the transformer works
When voltage is applied to a coil of wire, an electric current is created, just as water will flow through a pipe when the applied pressure is high. Along with the aforementioned, it is important to note that this is an electric current that creates a magnetic field on top of the coil, since this principle can be demonstrated by wrapping an insulated wire around a nail, and then attaching a battery to the ends of the wire. Also, when there are enough loops and electrical power, it can be said unequivocally that this will give the electromagnet the ability to pick up small metal objects, as any standard magnet can do. But along with the aforementioned, if the battery is replaced by a variable voltage source such as AC, the magnetic field will also change accordingly, yes, it is essential for activating transformer.
How does the transmission of electricity work in a transformer?
When we talk about how the transformer works, more than once the question comes up – what is the way the electricity is transferred in the transformer? Well, when there are two transformer coils that are next to each other and there is an electric current that flows through the primary coil, a magnetic field is actually created by transferring the electric power directly to the secondary coil. While the magnetic field changes over time, it actually combines with the secondary coil in order to create a kind of generator since a generator is a tool that produces electricity by moving coils through a stationary magnetic field. Bottom line, electricity passing through the primary coil is converted into a magnetic field which generates electricity directly to the secondary coil. At the same time, it is important to note that among the wide range of advantages of transformers, one of the most prominent advantages will be the fact that as energy costs rise, the greater the need for transformers in industry.
