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 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 step-up transformer increases voltage, while a step-down transformer decreases voltage.
A transformer is used to step up or step down a Voltage supply.
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
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
A step-down transformer reduces the voltage from a higher level to a lower level, while a step-up transformer increases the voltage from a lower level to a higher level.
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 used to step up or down the value of voltage.
