The step-up transformer steps up the input voltage to a higher level so that it can be transmitted over a transmission line using smaller conductors. By the power law, power equals volts times amps, so you can achieve the same power with higher voltage and lower current, but the wire size is based only on current.
On the other end, step-down transformers reduce the high voltage back to usable levels.
What else can I help you with?
What is the differences between a step-down transformer and a 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
What type of transfomer increases the voltage produced by the source?
step- up transformer
What statement correctly describes a step up transformer?
increase the amount of voltage
What is LV winding of a transformer?
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.
How could you convert step up transformer into step down transformer?
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.
How do you produce a step-up transformer in an ordinary transformer?
Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.
What is the purpose of transforms?
A transformer is used to step up or step down a Voltage supply.
What is the primary function of a step-down transformer that distinguishes it from a step-up transformer?
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.
What is the differences between a step-down transformer and a 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
What is the main function of a transformer?
step up transformer output gives the high voltage which is useful for transmiission of electricity
What is the main function of the transformer?
step up transformer output gives the high voltage which is useful for transmiission of electricity
Step up transformer is used to increase the?
A step up transformer is used to step up an AC voltage
What is the difference between a step-up and step-down transformer?
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
What is the difference between a step-up transformer and a step-down transformer in terms of their voltage conversion capabilities?
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
What type of transfomer increases the voltage produced by the source?
step- up transformer
How do you xxplain in a simple way function of stepup and step down transformer?
The function of a step up transformer is to step up the voltage given to it. For eg 11/32KV transformer steps up 11 KV to 32 KV. The function of step down transformer is to step down voltage For eg 420/230 V it steps down 420V to 230 V It does step up or down According to step up or step down ratio called transformation ratio k which equals to K=Ns/Np =Vs/Vp =Ip/Is ie ratios Ns:Np=Vs:Vp=Ip:Is=k Vs=secondary voltage Vp=primary voltage Ns=secondary number of turns Np=primary number of turns Is=secondary current Ip=primary current
What is step up tranformer?
A step-up transformer is a transformer that increases voltage that is transferred through power lines.
