Whether a transformer is 'step up' or 'step down' has nothing to do with the way its windings are connected, so it could be wye-delta or delta-wye.
step- up transformer
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
increase the amount of voltage
For a step-down transformer, its secondary winding will be the LV winding. For a step-up transformer, its primary winding will be its LV winding.
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
A step up transformer is used to step up an AC voltage
A transformer is used to step up or step down a Voltage supply.
A transformer that increases voltage is a step-up transformer.
Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.
step- up transformer
A step-up transformer is a transformer that increases voltage that is transferred through power lines.
They do not step up energy. They can step up voltage.
A transformer that increases voltage is a step-up transformer.
simple step up 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
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.
