It raises the voltage of the output of the main generator to the level of the grid transmission lines. The actual values depend on the design of the plant and grid system. In the UK the generator output would typically be about 23 kV and the grid line at 400 kV. Very high voltages make transmission of power more economical because the current is correspondingly reduced.
The function of the main transformer at a power plant is to step up the generator voltage to the transmission system voltage.
The purpose of a step up transformer is to take a voltage supply of one value and increase it to a voltage supply of a higher value.
step up T/F increase the supply voltage while the step down transformer decrease the supply voltage
Step up increases the voltage and a step down decreases the voltage from the primary to the secondary proportional to the number of turns in each winding.
Because higher power is more energy efficient to transmit along power lines than lower power.
the difference between a step up transformer and a step down transformer is that, in a tsep up transformer, the voltage secondary is greater than the primary side but in a step down transformer, the voltage secondary is lesser than the primary side
A transformer used to step up or down the value of voltage.
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
'CT' is used to designate current transformers, and 'PT' is used to designate potential transformers. A current transformer provides a ratio of primary current to the secondary. A potential transformer provides a ratio of primary voltage to the secondary. A power transformer (step up or step down) resembles a PT more than a CT.
It is a step up or step down for power delivery.
A transformer is used to step up or step down a Voltage supply.
Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.
the difference between a step up transformer and a step down transformer is that, in a tsep up transformer, the voltage secondary is greater than the primary side but in a step down transformer, the voltage secondary is lesser than the primary side
the main function of transformer is to change the magnitude of Voltage. difference between step up and step down is step up will change the input voltage into a larger magnitude of output while step down is vice versa
No. You can not step up power with a transformer. You can step up voltage, while stepping down current, or you can step up current, while stepping down voltage, but you cannot step up (or down) power.
You can go to ebay.com. Then sign up for an account and search for "step down transformer."
If the primary voltage (input) is less than the secondary (output) then it is a step-up. If the input is greater than the output then it is a step-down transformer.
If the voltage needs to be increased from a lower voltage to a higher voltage a step up transformer is used. If the voltage needs to be lowered from a higher voltage to a lower voltage a step down transformer is used.

A transformer is a static device which is used to step up or step down the voltage in a powered circuit.
