it decreases the high input voltage of its primary winding to a voltage level on secondary winding suitable for usage
It is used when u need to step up or step down a particular voltage level.
Step up transformers, and step down transformers
Power transformers are step-up or step-down transformers used in the electricity transmission system, whereas distribution transformers are step-down transformers used in the electricity distribution system.
It depends on the type of transformer:transmission/distribution transformers step up or step down system voltagesisolation transformers electrically isolate two systems without affecting their voltagesmatching transformers are used in electronic circuits for impedance matchinginstrument transformers step down voltages (voltage transformers) or currents (current transformers) for measurement or protection applications
Transformers are an important part in the electrical distribution network. They step up or step down electricity.
Generators generate and transformers step up or step down the voltage
transformers are used to step up or step down the voltages
to step up voltage or to step down voltage
Step-up and Step-down transformers
It is a step down transformer which is used to supply the electrical power to the station transformers and the colony transformers
Transformers can be used in either step-up mode or step down mode, they are just as efficent connected either way. Most large transformers have percentage "taps" to allow voltage corrections up or down by about 15%.
