Step-down transformer is used at grid substations for feeding various substations which further step down the voltage for feeding distributing Transformers and further step down transformers are used to supply the voltage for the consumer uses

What type of transformer is found outside a residential house?
Stepdown Transformer.
What is 660VA for stepdown transformer capacity?
the maximum power it will supply
What kind of transformer do i use to run LED?
A step-down transformer U really don't need a step up or stepdown transformer You need a source capable to run your LED it can be a swithcing power supply for istance a battery
Why transformer is used?
A transformer used to step up or down the value of voltage.
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
What type of transformer is found outside a residential house?
Stepdown Transformer.
What does a step up transformer do at a powerplant?
It is used to step up the voltage in order to transmit it a long distance where it goes into a stepdown transformer and then into your home .
Does 110 volts cost more if uses stepdown trasformer?
If you have to pay for the stepdown transformer, yes. If that is provided free, there is a small loss of energy in the transformer, maybe about 5%, and it depends on whether the meter is installed before or after the transformer.
What is 660VA for stepdown transformer capacity?
the maximum power it will supply
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.
Can a 240V - 110V stepdown transformer be reversed to take a primary load of 180V to secondary 240Volts?
No
What happens if a 208VAC primary voltage is connected to a 240VAC stepdown transformer to 208VAC?
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
Is there a way to install a 120V light on a 277V circuit?
no ----------------------------------------------------------------------------------- Stepdown transformer. More expensive than buying the correct light fixture. Y-THINK-Y
What kind of transformer do i use to run LED?
A step-down transformer U really don't need a step up or stepdown transformer You need a source capable to run your LED it can be a swithcing power supply for istance a battery
What do I need to do to convert 9 volts ac to 6 volts ac?
The "pat" answer is a stepdown transformer. But finding one that does this in this voltage range is not going to be easy. It's an "odd duck" in the world of voltage conversion. There are other approaches that might be used, but more knowledge of the project or application would be needed to make suggestions.
How do you convert 24volts to 12 volts?
If you want to convert 24v AC into 12v Ac, it's simple. Just get a transformer to convert 24 volts into 12 volts. This is called a stepdown transformer. If you want to convert 24v DC into 12v DC, it's more complicated. First you have to change the 24v DC into 24v AC by a switching converter that changes DC into AC. Then you would use a stepdown transformer as in the former example. Once the 24v AC is converted to 12v AC, then you use a rectifier bridge to change the 12v AC into 12v DC.
What are stepdown transformers used for?
A step-down transformer accepts a given voltage on the primary winding (coil), and outputs a lower voltage on its secondary winding. A good example is a doorbell transformer you might buy for your home. It uses 120 volts from the house electrical system and steps it down to a safer 18 volts used to ring the doorbell. The voltage produced is a function of the 'turns-ratio' of the transformer. For example, if the transformer has 500 turns of wire in the primary, and 125 turns of wire in the secondary, we would say it has a turns ratio of 4:1 (pronounced "four-to-one"). If we feed 120 volts into the primary, the secondary would produce 30 volts. 120:30 = 4:1
