What will be the output if you apply a single phase on all three wires of supply side of a transformer?

Your question is confusing because you give absolutely no information on the transformer, such as its turns ratio, or any information about the supply voltage. Presumably, though, you are describing a three-phase transformer, as you refer to three wires? Again this is confusing, because you do not describe how you would supply single phase to 'all three wires'!

What will happen if apply two phase supply to a three phase transformer?
A three phase transformer is simply three transformers so, supplying one phase to a set of three transformers will result in only one phase output. Any loads connected to that transformer that are expecting three phase power will malfunction, and could fail.AnswerA three-phase transformer is NOT 'three separate single-phase transformers', as suggested in the original answer. It is a single transformer with three primary and secondary phase-windings wound around a common three-limb ('core') or five-limb ('shell') core. If a single-phase supply was applied to one of the three primary windings, then single phase voltages would appear across each of the three secondary windings and the remaining two primary windings. These voltages would not be out of phase with each other.
Why transformer cannot work on dc voltage?
In DC, flow of current is controlled by resistance only where as in AC it is done by Impedance which is combination of Resistance , inductive and capacitive reactances.Reasons:In transformers resistance of the transformer's core windings are very low due to which if you will connect transformer across DC supply then it will draw a heavy current which will burn out is winding and it may damage the equipment too.Transformers works of the principal of Induction (Mutual/Self) that is possible in AC only because in DC there is no induction therefore even if transformer's windings anyhow withstand with DC there will be no voltage output at output terminals of the transformer, therefore it is useless to connect transformer on DC supply.
How can you use step down transformer of 240 v ac to 24 v dc as step up transformer?
A step down transformer has a higher voltage (in this case 240v) primary and a lower voltage (in this case 24v) secondary. A step up transformer has a lower voltage primary and higher voltage secondary. In reality the transformer doesn't care which is which, so if you wire the 24v side as the primary and the 240v side as the secondary, you have a step up transformer. You might want to stick a fan on it to be sure it doesn't overheat, but that's all you need do.AnswerFrom your question, it sounds as though you are describing a power supply, rather than a transformer, as you specify the output is 24-V d.c. (direct current). Unfortunately, you cannot apply 24-V d.c. to the output side of a power supply, in order to obtain a 240-V a.c. output at the input side! This is because a power supply consists of a transformer to step down the a.c. voltage, and a rectifier (and, possibly, a smoothing filter) to produce a d.c. output. Applying d.c. to the input of a rectifier will not produce the a.c. necessary to run your transformer in the opposite direction!
What are the applications of equivalent circuit of a single phase transformer?
Equivalent circuits allow you to treat the transformer itself as being 'ideal', while treating its losses, etc., as external elements to which the normal laws of networks apply.
How do you measure the volt-ampere rating of a transformer?
No need to measure, on the side of every transformer is a nameplate with all the transformer's specifications. Primary and secondary voltages, impedance and winding ratios. Need more info. What are you trying to do? If it is a small transformer - such as a one that is soldered onto a printed circuit board in a radio or a computer power supply- then it may not have any nameplate. If it is that type of transformer it will have been designed to do its job and you would not need to be able to measure its volt-amp rating. If the transformer is of the larger type that runs on household mains voltage that was mounted separately inside some equipment - such as an old battery charger, television, etc. - then you would have to use some suitable lab test equipment to be able to apply a variable load to its secondary winding (or to the appropriate tap on an auto-transformer) whilst measuring its output voltage and body temperature.Such tests should never be attempted unless you really know what you are doing and have the right test equipment to be able to do it safely. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How transformer get burn?
Current overload from whatever circuit draws current from the transformer? Proper fusing of its supply might protect a transformer from this cause. Or it could have developed a shorted turn fault because the insulation on a winding got old and perished? Or maybe the transformer got damaged if the appliance it is mounted in was dropped?
Where you r not apply ohms law?
in transformer
Why does your power drain as soon as you put a load on it?
It could be a couple of things. Voltage drop is one, if the distance of the load is too far from the source of power this will happen. The other thing is if you are using a step down transformer and it is under sized, as soon as you apply the load the transformer output will drop off. If this condition lasts the transformer will eventual fail.
How can you find primary from secondary coil?
Primary and secondary are only terms of convenience based on the ratings and purpose of the transformer. If a transformer is labeled 120 to 240 volts, just pick a winding and apply 120 VAC. If the output is 240 volts you found the primary and secondary. If you apply 120 volts and get 60 volts out that means the side where you applied 120 VAC is the secondary.
What happens when load is given to primary side of a transformer?
The Load will consume part of the power and therefore reduce the current (voltage ) available for the secondary part of the transformerAnswerYou cannot apply a load to the primary of a transformer which, by definition, is the winding connected to the supply voltage. Your question makes no sense.
What are the primary winding and secondary winding of a transformer?
The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. The terms, 'primary' and 'secondary' are unrelated to voltage levels.
What happen if you apply triangular input to transformer?
there will be no neutral point in the circuit and high voltage will be across the transformer coils
