The world has changed a lot and everyday at least one invention or technology is happening in the world. Every equipment or device around us is running on electricity, even the vehicles are now using electricity as a fuel.
Now we are at a stage where we cannot imagine our lives without electricity. Today we are in a world where every device around us is running on electricity and the transformer is playing one of the important roles in the distribution of electricity.
What is an Electrical Transformer?
Transformer is one of the most valuable inventions and it is used to transfer electricity from one circuit to another circuit without changing its frequency. The transformers are used for altering the voltage, to increase the efficiency of the power system and to improve the safety.
Transformers are used everywhere, but most of the applications of transformers are in residential and industrial areas. Basically, an electrical transformer works on the principle of Faraday’s electromagnetic induction. At Vajra Transpower Pvt. Ltd., we manufacture all types of transformers and it is the best transformer making company in India.
Function of Transformer
Transformer works on the principle of Faraday’s Law of Electromagnetic Induction, and Faraday’s second law states that when a conductor is placed in a varying electric field, then an EMF will be induced. The main components of a transformer are primary winding, secondary winding, and transformer core.
Electric flux is produced when current flows through the primary circuit, then it will move across the transformer core. Then, due to electromagnetic induction law, the flux will generate current in the secondary coils. In this process, there will be no change in the frequency.
- To step up or step down the voltage by maintaining the frequency constant and also balancing the power in the same level.
- The number of turns of winding on the primary and secondary coils will decide the change in the voltage levels.
- The transformer which is used on the generating side will increase the voltage level and therefore it is called a step-up transformer.
- The transformer which is used on the load end will decrease the voltage level and therefore it is called a step-down transformer.
- Generally, the power generated will be of different voltages like, 3.3/6.6/11 kV. But while transmitting the power from one end, i.e. from the generating station to the end users.
- While transmission of power, in order to reduce transmission line losses, the voltage is stepped up at generating substation to high levels like 66/132/220/400 kV. The transformer used here is a step-up transformer.
- The high voltage power cannot be used, so the voltage should be decreased. Here, a step down transformer is used to reduce the voltage to 3.3/6.6/11 kV.
Application of Transformer
Transformer has many applications in different fields or areas. Mostly, transformers are used for industrial purposes, and they play a key role in many industrial aspects or processes. In industries, transformers are used to ensure appropriate, safe, and careful usage of power. It will help to prevent the damage of industrial equipment and also to protect the people working around it.
- In the electrochemical industries, transformers play an important role in the process of electrolysis of different elements in the electroplating process.
- In steel manufacturing industries, to bear the constraints of a steel furnace like mechanical, thermal, dielectric, etc. transformers are used. Transformer helps to maintain safe supply of electricity and also to ensure high voltage supply safely.
- Apart from these industries, transformers are used in the industries like military, biochemical, aerospace, manufacturing, and many more.
Points that you need to keep in mind while choosing a transformer
Purchasing a transformer is not an easy task, there are certain points or factors that you need to keep in mind when purchasing a transformer.
- There are two types of transformers like single phase and three phase transformers. For household use, single phase is the perfect choice and for commercial and industrial use three-phase is most suitable. So, choose according to your needs.
- When choosing a transformer, choose according to the kVA requirements. If a huge load has to be maintained, then a transformer with high capacity must be selected.
- The voltage requirement and frequency requirement is also very important, so while choosing a transformer choose based on the requirements.
- According to the location of use, you can choose a transformer. There are transformers that are designed according to the location requirements.
So, these are the things that everyone must know before choosing a transformer.
