A single-phase transformer works with a single-phase supply, while a 3-phase transformer is used with a 3-phase supply.
A single-phase transformer has 2 wires on the primary and secondary (ignoring taps) while a 3-phase tansformer has 3 or 4 wires on the primary and secondary.
What else can I help you with?
What is the current of 1MVA transformer?
This depends on the voltage, and whether it is a three phase or single phase transformer.
Load test on single phase transformer?
The dc tests that can be done on a transformer are to measure the resistance of each windings and to measure the insulation resistance between the windings and between each winding and the transformer case.
How do you design a transformer with three phase 400v input and single phase 2000v output?
By design are you going to wind the transformer yourself? In your design you need a 5:1 ratio. On the output side of the transformer any two legs of a three phase transformer is considered single phase voltage. Good luck on your project.
How do you change 3 phase to single phase for Henny Penny display warmer?
You can go to an electrical supply store and purchase a transformer that will work for youAnswerA single phase supply can be obtained by connecting the load between any pair of line conductors, or between one line conductor and the neutral -depending on the nature of your three-phase supply. The single-phase voltage must match the rated voltage of your warmer, otherwise you must use a transformer.
Would you install three-phase transformer or bank of three single phase transformer in a large power station and justify by comparing the two schemes?
A three-phase transformer bank is often used in power stations because it is easier to construct and transport very large single-phase transformers, compared with constructing and transforming an equivalent-capacity three-phase transformer.

How do you convert a 3-phase system to a single phase?
By having a transformer with 3 phase input and single phase out put
Why the need of harmonics in single phase transformer?
Harmonics are really not needed in single phase transformers.
What is this system called with three single phase transformer?
Your question is rather vague. If you are asking what do you call a group of single-phase transformers, connected to supply three phase, then the answer is a 'three-phase transformer bank'.

Is there a basic difference between a three phase power transformer and a three phase distribution transformer?
The basic difference is the secondary voltages. On a distribution transformer the secondary voltage is very high. This is to overcome line loss for transmission of electricity over long distances. A three phase power transformer is used at the consumers three phase services end to manipulate voltages that consumers need to operate their equipment. The transformer that feeds your house is considered to be a single phase power transformer.

How do you test a single phase transformer?
with an meg ohm meter

Can 3 single phase transformers can replace 1 three phase transformer?
Yes, you can use three single phase transformers on three phase applications and interconnect them to serve as a single transformer or you could use one single phase transformer fed from two of the three lines in a step down application.
How many 16 Amps per phase welding outlet can you install to a 30 KvA rating transformer?
..the questions does not say wether the 30kVA transformer is 3 phase transformer or single phase transformer..but it is implying that a single phase welding load at 16A per phase is to be connect to it, it is assumed then that the transformer is 3 phase transformer..we assume load is rated 240V.. ..though not much details is given about the transformer voltage specs. but if is rated 3 phase 415/240V, the approx full load current per phase is given by 30KVAx1.3912=41.736A.. ..but if the transformer was rated single phase 240V say, the approx full load current FLC=30000/240V gives 125ampers.. ..if you further devide the FLC by the intended load current.. ..Recommended no of welders per for a 3 phase 415V transformer and assuming single welding sets =41.736/16=2.6..so you can connect max two welding sets to this transformer per phase,..max 6 weld sets can connect at an approx load factor of 76%.. ..for the single phase transformer, FLC/16=125/16, gives 7.8 but is also recommended not to connect more than 6 welding sets to such transformer for the same reasons..
