An Introduction To Transformers
Have you ever thought of, what is a box type device installed in almost every house hold appliances? Well, that is a transformer used to couple electric energy from one circuit to another with the use of inductively coupled capacitors. Common areas where transformers are used can be like TV, ceiling fans and your electric motor that is used to fill up the overhead tank.
The working principle of the device is mutual inductance. The phenomenon says that when a current carrying conductor is forced to vary its current, it produces a varying magnetic field in it. Therefore, a current of same value is then induced into the coil that is placed near to the conductor. And so, these two coils are known as primary winding and secondary winding respectively.
There is a long list of advantages that a transformer offers. Some of them are listed as under. When electricity is generated at the power station, the voltage is very high which can't used for commercial purposes. Hence, step down transformers lower the voltage and is then distributed to you.
As stated above, step up transformers are used to increase the voltage level of the power that is generated at the power station and the areas where a less power is required, are served by step- down transformers. For example companies, enterprises and business areas have large power requirements.
Appliances such as washing machines, dishwashers, cell phones use transformers for their effective working. Not only this, two way conversation is possible on your single cable telephone set is mainly due to transformer.
Microphones and record players use signal and audio transformers to couple different stages of amplifiers.
Besides, this electrical device is very advantageous in day to day electrical circuitry. Transformer core, coils, capacitors, inductors, oil tank etc are some of the parts of a transformer which are not very expensive. Thus, the device is not that costly. Transformers that consists of only one winding are also available. Such type of transformers are termed as auto transformers. These are the least expensive one since, these have only one winding.
Another important benefit that device offers to both the user and the equipment in which it is used is its faster switching time and higher efficiency.
