Electrical generators work at about 11,000 volts which is not enough to transmit power over long distances over about 5 miles. Therefore step-up Transformers are used to connect them to the local grid on 132 kV or the supergrid on 275 or 400 kV (in the UK)
Step-down transformer is used at grid substations for feeding various substations which further step down the voltage for feeding distributing transformers and further step down transformers are used to supply the voltage for the consumer uses
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.
A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage. You'll see transformers at the top of utility poles and even changing the voltage in a toy train set.
transformers are used to step up or step down the voltages
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
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
Well, honey, the step-up transformer in the national grid is typically located at the power station where electricity is generated. This transformer is responsible for increasing the voltage of the electricity before it is transmitted over long distances through the transmission lines. So, if you're looking for it, start your search at the power station - it's not exactly hiding in plain sight!
Most electrical transformers are used to step up or step down the voltage of alternating electrical current.
step up transformer
Transformers, step up or step down, use mutual induction in their operation.
It is used when u need to step up or step down a particular voltage level.
