A transformer that is for a single phase, or wire set (hot and return). Any small electronic device that you plug into a wall socket likely uses a single phase transformer to step the outlet voltage down to 5-24 volts.
a transfer is a static piece of equment used ither for rising or lowering the voltege of an a.c soply with correspond incrise or decrise current .

What is the current of 1MVA transformer?

This depends on the voltage, and whether it is a three phase or single 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'.

How you differentiate between single phase and three phase transformer?

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.

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 test a single phase transformer?

with an meg ohm meter

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.

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..

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.

What transformer do you need if you have primary voltage of 600 3 phase and require 240 volt 1 phase?

A single phase 600 to 240 Volt transformer using two phases of the three phase primary.
