Step-up Transformers used in the transmission of electrical energy increase the voltage going over Transmission Lines (over 100,000 Volts). For a given amount of POWER to be Transmitted, the higher the Voltage, the LOWER the CURRENT. This reduces the amount of Power LOST to the Resistance of the Transmission Lines.
Power Lost is calculated by the Formula:
POWER Lost = I2 x R, where I=Current and R=Resistance
So, the lower the Current (I), the lower the transmission line losses.
At the end of the Transmission Path the Voltage is "Stepped Down" to a value usable for the Customer, usually (220 volts for Residential use in the USA).
Step up and step down Transformers are used to increase and voltages. There are many reasons why different levels of voltage are required. E.g., high voltage is needed to transmit electricity large distances to avoid losses. Low voltages are used to make electricity safer for use with toys, like electric trains.
At high voltage the resistance of the supply cables has less of an effect therefore the power can be sent over long distances and then transformed back down to normal voltages.
step up transformer
Step-up transformers of the type you describe are three-phase transformers which, in the transmission system, are classified as 'power transformers'.
Step up transformers increase the voltage, while step down transformers reduce it. Higher voltages are better for electricity transmission/distribution, because, for any given load, the higher the voltage, the lower the resulting current. This means the supply conductors can have a lower cross-sectional area and the resulting saving in copper makes the installation cheaper. A lower load current also means lower line (energy) losses.
On the whole AC electrical conversions are done with transformers. In your question both step up and step down transformers will be utilized. Step up transformers will be utilized to get the generated voltage up to transmission voltage. At the voltage transmission destination the voltage will use step down transformers to decrease the voltage to the consumers load requirement. Or you could connect 111111 resistors in series and take the voltage off each one of them .. but ull have to put in consideration the load resistance ..
The transformers step-up and down voltage for transmission and use.
(This is what my teacher said, I wrote this down in my notes) The answer is, Step-up transformers are used to increase the voltage of an electric current before it is sent out over transmission lines from the electric company. Step-down transformers are used to reduce the voltage of current from high-voltage transmission lines before it enters homes and businesses. Some devices, such as televisions, contain step-up transformers that increase the voltage once again.

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.

"Electric" transformers are used in the electric power system for many things. I wonder if you mean "auto" transformer. Transformers are used to step up/down voltage and currents, to provide a ground reference, to inject signals onto power lines, to sample high voltages and currents, etc.
it is basically the transportation of electrical power from the power generation plant (eskom) via step up voltage transformers to the substation (step down transformers. to the distribution of the consumers.

Step up transformers, and step down transformers
The transformers step-up and down voltage for transmission and use.
It is used to transform the power. It is dived into two types...Step UPStep DOwnand again it is classifed into 2 based on voltage to transform or current.AnswerThe benefit is straightforward. Without transformers, electricity transmission and distribution would be impossible. For the transmission of electrical energy, very large voltages are required, and the only efficient and economic way of doing this is with transformers.
