Where are power transformers used?
Power transformers are used in the high voltage transmission network to step up and step down the voltage. These transformers are generally used for the purpose of transmission of heavy loads.
Where can transformers be found?
Transformers are found everywhere Alternating Current (AC) electrical energy is used. A transformer is an electrical device that trades voltage for current in a circuit, while not affecting the total electrical power.
What are the applications of power transformers?
Applications of Power Transformers:
- Conductor or turn-to-turn insulation,
- Coil-to-coil insulation,
- Low voltage coil-to-earth insulation,
- High voltage coil-to-low voltage coil insulation, and.
- High voltage coil-to-ground insulation.
Where are transformers used in everyday life?
Transformers are employed for widely varying purposes; e.g., to reduce the voltage of conventional power circuits to operate low-voltage devices, such as doorbells and toy electric trains, and to raise the voltage from electric generators so that electric power can be transmitted over long distances.
Which is a power transformer?
Power Transformer Definition. A power transformer is a static machine used for transforming power from one circuit to another without changing the frequency. As there is no rotating or moving parts, a transformer is classified as a static device. Transformer operates on an AC supply.

What is an example of a transformer?
An example of a transformer is a fictional creature that changes from a person into a dog. An example of a transformer is a device that uses electromagnetic induction. The magnetic field produced by an alternating current in one coil induces a similar current in the other coils.
What are power transformers?
Power transformers transform electrical voltage from one level or phase to another, usually “stepping down” voltage ratio from a higher to a lower level. This is accomplished through the principle of magnetic induction between coils to convert voltage and/or current levels.
Do transformers change AC to DC?
A transformer cannot convert AC to DC or DC to AC. The transformer has the ability to step up or decrease current. A step-up transformer is a transformer that raises the voltage from the primary to the secondary. The voltage is reduced from primary to secondary by the step-down transformer.
What are the parts of power transformer?
The main ones are the windings, tap changing system, core, tank and bushings. The components are assembled together to produce a power transformer.
