Can a 400-110v step-down transformer be reverse-connected to the secondary of an 11kv-110v transformer to obtain a 400v 3-phase and neutral output from an 11kv mains panel to make an AMF mains input?

Possibly... but only a trained electrical technician would be licensed to do that kind of work!

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
A transformer is used to step down a voltage of 11kv to 220 volts. Given that the primary coil has 3200 turns what is the number of turns on the secondary coil?
Your 11 kv to 220 volts represents a 50 to 1 stepdown. (There is 50 times more voltage in the primary than in the secondary.) You'll have to have a 50 to 1 turns ratio. That means 1/50 of the number of turns in the primary will be in the secondary, and that is 64 turns.
When a transformer steps down a power source what will remain the same the frequency the voltage or the current or none of these?
The frequency remains the same as one cycle in the primary corresponds to one cycle in the secondary.The stepdown voltage on the secondary as a ratio of the voltage on the primary will be the same as the ratio of turns in the primary to turns in the secondary.The current in the secondary depends on two things: the current that the load is taking at the lower voltage of the secondary and the relative thickness of the wire in the secondary to the thickness of the wire in the primary.ANSWER: A transformer does not step up/down a power source ever it does however step up/down the voltage related to the primary. A typical transformer will always have an efficiency loss. The frequency on the output will remain the same as the input. It is not true that the big wires will give you more current that would be true only if the iron core is increased accordingly. otherwise saturation will occur
Can a 240V - 110V stepdown transformer be reversed to take a primary load of 180V to secondary 240Volts?
No
What type of transformer is found outside a residential house?
Stepdown Transformer.
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
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 .
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.
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.
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 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

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.
