Determine the type you need (primary voltage, secondary voltage, power rating in volt amperes - not watts, size, etc.) then check a catalog at an electrical or electronics parts store for a standard transformer meeting your requirements. If you find one and the store stocks it, buy it; if not have them order it for you.
If there is no standard transformer meeting your requirements, one would have to have a company that custom winds Transformers design and build it for you. Unless you would be buying in quantity, this will be expensive.

∙ 15y agoStep up Transformers are used where the voltage being supplied through the primary line needs to be increased to a defined level to be supplied to the load.
Step up Transformers are basically used for enhancing the voltage level.

∙ 14y agoits a simple transformer which converts say 110volt 60hz ac current to 220 volt 60hz ac current. such change in magnitude of ac current from lower value to higher value is know as step up operation. if it vice versa then its called step down

∙ 14y agoStep up Transformer is used in the long distance transmission.
Here is the example :
The generating stations are located at favorable places, generally quite away from the cities. At the generating station , the A.C. generator produces moderate voltage (say 11kV). It is stepped up to a high voltage (say 220kV). Prior to transmission. The A.C. power is then transmitted at this high voltage . Upon arrival near the outskirts of the city ,the voltage is stepped down to convenient level (say 11kV).The 11kV lines are run through the city for further handling by sub stations located at various parts of the city.

Step up transformer is used to increase the?
A step up transformer is used to step up an AC voltage
What is used to increase or decrease voltage that enters a house?
A transformer can be used, either a step-up or step-down transformer, to deliver the power at a different voltage from the normal supply voltage.
How do you convert 480v to 120v?
to derive 120 volts from 480 volts you have to use a transformer, based on your needs. If you needed 100 amps at 120 volt single phase you would need a 12kva transformer. This is just an example.
Can you use a step up transformer on a 110 and safely power a cooktop that requires 220?
Generally,no, you can't. Most 110-volt outlets provide only a limited amount of current, normally in the range of 15 amps (maximum). In that case, the maximum power output of the outlet is about 1800 watts. Most 220-volt cooktops I've seen require twice to four time that amount of power, with some power requirements reaching 12 kilowatts (12 kw or 12,000 watts). But these large power users are mostly 36" induction cooktops.In the case of attempting to operate a 220-volt cooktop on an "standard" 110-volt electrical with a stepup transformer, the outlets you have could not begin to provide the required power. If you do the math, you'll find that even attempting this is a very bad idea. Consult an electrician for conformation. No professional electrician would even submit a bid to you to do this job (powering a 220-volt cooktop from a 110-volt circuit with a stepup transformer). They'd tell you over the phone that it isn't something that will fly past the electrical code.
Can a 500mA transformer be used to operate a circuit requiring 1amp12w?
No because that transformer can only supply a ½ amp so it would seriously overheat if a 1-amp load was connected to it.
Why not stepup transformer is not used in rectifiers?
Rectifiers turn A/C into D/C, but transformers can only run on A/C.
How a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
What is transformer w?
Transformer is a electric device which it can be used for to transfer the ac current one circuit to another i.e. To reduces voltage and without frequency changing. Many types of transformer available in various purpose i.e. Stepup transformer, stepdowntransformer ,autotransformer ,,,,,,,etc answered by arivukkarasu.a
What is stepup transformer?
A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.
Why stepup transformer uses ac?
Confusing question! If it is, why transformers use ac? Then it is, for induction there must be change in flux linkage which is possible with ac which frequently changes polarity. In dc there wont be any change. If que is, why step up is used? There will be considerable voltage drop with distant transmission. For this reason step up voltage is required with step up transformer. Since, in high voltages this drop is negligible or efficient transmission
What is the difference between step up and step down?
in transformers for instance a stepup transformer does exactly that, steps up the voltageAND/OR theamperage and a step down transformer reduces the same. if you have a machine that operates on say 120 volts alternating current single phase and your building or power supply in your buildingis set up for or delivers480 volts alternating current-three phase you will need a step down transformer to operate the machine.
What does a step up transformer increase?
Power is normally transmitted at high voltage through step up/step down transformers to minimize the power losses in the transmission lines (this is one reason anyway). Since power loss is equivalent to the resistance of the conductor times the current squared, stepping up the voltage by a factor of two cuts the transmission losses by a factor of (2^2 = ) 4.
Why transformer is used?
A transformer used to step up or down the value of voltage.
What is the transformer used in ups?
simple step up transformer
Oil filled transformer is usually used indoor or outdoor?
An oil filled transformer is usually used outdoors and a dry core transformer is usually used indoors.
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
What is the difference between control transformer and Potential transformer?
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
