What do you need to know about electrical transformers?
Electrical transformers are equipment that controls power/voltage supply in the surrounding electrical environment. But what else do you know about them? Read the conversation between Mr. Pranay, owner of a transformer manufacturing unit and his daughter for a better understanding of electrical transformers.
Mr. Pranay and his daughter, Jyoti were on a night stroll when his daughter saw a transformer in their residential area. She was fascinated to see big metal equipment, big electric poles, connected with multiple wires and asked her dad about the same.
Jyoti: Dad, what is this huge equipment on the roadside?
Mr Pranay: Jyoti, this equipment is a transformer, electrical transformer. And that’s wht we manufacture at our factory.
Jyoti: What is a transformer and why do we have it in our colony?
Mr Pranay: Dear, a transformer is an electrical component that is used to alter the voltage of electric current we have at our homes. This equipment is installed in our colony for transporting the electricity to every household in our colony. Plus, it steps down the high-intensity voltage from generation plants to the usable low-intensity voltage.
Jyoti: What are the basic characteristics of a transformer?
Mr Pranay: Irrespective of their types, every transformer showcases a few common features, like:
- Every transformer works on the laws of electromagnetic induction.
- The input and output power frequency is the same.
- They don’t need a movable component for energy transmission.
- Both primary and secondary coil/windings are devoid of electrical connection.
- All of them experience energy losses, which can be controlled by designing energy-efficient transformers.
Jyoti: Are all transformers of the same size?
Mr. Pranay: No, dear. Transformers can be constructed in different sizes, with different materials, for different power requirements and of different types.
Jyoti: What are the most common types of transformers, Dad?
Mr Pranay: The common transformer types are: Power transformers, Distribution transformer, and Three-Phase transformers; all of these are deployed toStep-up/Step-down voltages.
Jyoti: Why do you manufacture so many different types?
Mr Pranay: Because every transformer type has a different application.
Power transformer is installed for smooth current transmission between generation plants and distribution channels.
Distribution transformers are used for primary and secondary distribution to the end consumers.
Step up/down transformer:A transformer that is used for modifying the voltage/current while transmitting the current in the distribution channels. Step up transformers increases the voltage levels. Whereas, the step down transformer decreases the voltage level during the transmissions.
Jyoti: But why is this equipment so huge? How many components are used in it?
Mr. Pranay: Jyoti, transformers vary in sizes according to their usability. You will find a small-sized transformer in a stage microphone. Whereas heavy ones for generation and distribution. So, all the transformers are not necessarily huge. And, the answer to your next question is three. A magnetic core, primary windings and secondary winding.It uses many more components, variable to the type and application of the transformer.
Jyoti: wow Daddy. I would love to learn more about transformers the next time we get a chance.
Mr. Pranay: Sure Jyoti. You can visit our manufacturing plant anyday.
This conversation sums upthat transformers as a component perform multiple functions for its users. This crucial equipment not just transmits electricity, but also prevents energy losses, safeguards against energy failures and hazards, and alters electricity according to the end-user (industry, household, power plants, etc.).
