Can a 240v - 110v stepdown transformer be reversed to supply from180V stepping up to 240Volts?

Transformers can be reversed but their ratio remains the same. In this case a 240 to 120 volt step down transformer has a ratio of 2:1. By reversing the transformer and using 180 volts on the secondary side, there would be a potential of 360 volts on the primary side of the transformer. Also by using the higher voltage on the secondary side, stepping up will drive the primary side voltage above what the insulation factor that is recommended which is 240 volts.
A 240/120 v transformer is designed to run at that voltage, and it is dangerous to operate it at a significantly higher voltage because there will be appreciably higher magnetic flux in the iron core, leading to higher power dissipation and a potential fire hazard.

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 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
Is it possible to decrease voltage from 1562v to 30v using stepdown transformer?
Transformers step voltage up or down, so yes this is possible. This is a change of 1562/30 = 52, which is pretty high. It may be difficult to find a transformer made for this purpose. I've never heard of 1.56kV as a standard voltage. This seems a strange voltage. What is this coming from? A; Yes considering that a sub station will take transmission hi voltage to 16kv disribuition. and finally 240volts for us. the only consideration is breakdown and efficiency.
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 happens to voltage when current is increased?
current is decreased Depends of the circuit or device: in a stepdown transformer: power in= power out, V x I = V x I , Increase voltage in (power remaining constant) you current output will increase.
