Step down transformer is used by electric authority while distributing electricity.
Step up transformer is used :
- In household electrical appliances. For example: TV,fridge etc.
- In office to maintain potential for computers.
- In factories and industries.
Step-up and step-down transformers use electromagnetic induction to convert voltage between two circuits. We use both types in the distribution of power from supply stations to the end user, as well as to ensure that the appropriate voltage goes into a circuit on many personal devices.Step-up transformers are used at power stations to produce the very high voltages needed to transmit electricity through the National Grid power lines. These high voltages are too dangerous to use in the home, so step-down transformers are used locally to reduce the voltage to safe levels.

Transformers are used virtually everywhere, including power generation plants, industrial factories, commercial spaces, and residential areas. They can be as tall as a multi-storey building, or even small enough to fit inside an electric toothbrush.
A transformer can fail for a variety of reasons, but the most common causes include lightning strikes, overloading, wear and corrosion, power surges and moisture. Regardless of the cause, the result can be remarkable. Transformers contain mineral oil keeping the transformer cool.
