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.
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.
Why frequency is constant in a single phase transformer?
a transformer or inductor or capacitor does not change frequency frequency is controlled at the generating station with the speed of the motor or turbine the number of phases will not make a difference an inductor or capacitor can shift phase up to 90 degrees you can make 3 phase power from single phase power with inductors capacitors and transformers
What is Advantage of 3 phase transformer?
The type of transformer is dictated by the type of supply. A three-phase supply is used in power distribution because it dispenses with half the wire and therefore half the power losses in the circuit. In principle a three-phase transformer could be replaced by three separate single-phase transformers to provide the same service, but there would be double the mass of transformers, in other words the three single-phase transformers would be twice the weight of the three-phase transformer.
Can you get a 3 phase supply from single phase and how?
No, you cannot get a three phase supply directly from a single phase supply. Nowadays electronic inverter units can be bought that will do the job. For very low power loads the cost of such invertors is quite reasonable but for high power loads they are very expensive. For high-power industrial uses the most economical solution is to have a 3-phase service installed by the local electric power utility company.

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 can you step down a 15kv transformer single phase to 220v?
A transformer steps the voltage of an electrical power supply up or down. The transformer must be correctly designed for the voltage and current levels that it is intended for. Only ac can be used with a transformer, which is designed to work at a particular frequency.

What does filter do in a transformer?
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
Is an transformer or rectifer in a PC power supply?
Rectifer

What is the advantage of an open delta transformer?
An open-delta connection is a method of providing a three-phase supply, using two single-phase transformers. It is particularly useful if , say, one single-phase transformer, part of a three single-phase transformers forming a three-phase transformer bank, becomes damaged -allowing the two remaining transformers to provide a temporary three-phase supply to the load. The drawback with this connection is that the capacity of the transformer bank is reduced, and it can only provide a lower load current.
What is the difference between single phase transformer and three phase transformer?
Single phase transformers have one primary and one secondary winding, handling single phase AC power. Three phase transformers have three primary and three secondary windings, distributing three phase AC power efficiently. Three phase transformers are more commonly used in industrial settings due to their ability to handle higher power loads.
Can a single phase supply be used in a three phase supply?
No, a single-phase supply cannot be directly used in a three-phase system. The voltages and phases are different, so additional equipment such as a phase converter or transformer would be needed to convert the single-phase supply to match the requirements of the three-phase system.
Does open delta three phase transformer connection is used to convert three phase to two phase?
Two phase is not used anywhere. What you may be thinking is center tapped single phase (negative voltage at one terminal, neutral at 0, and positive at the other, all in phase so you can get 120 volts or 240 volts). Open delta would be used for three phase power. A single transformer can be used for single phase power. If you have limitted three phase power, and mostly single phase power needs, two transformers could be connected to provide both.Another AnswerAn 'open-delta' connection is used to provide a temporary three-phase supply to a load, from a three-phase transformer bank when one of the transformers has been removed due to failure. Linesmen can rewire the remaining two transformers in such a way that they still provide a three-phase supply, albeit at a reduced capacity.The open-delta connection can also be used to provide an initial (lower-cost) three-phase supply to a load when an increase in that load is anticipated at some time in the future. Adding a third-transformer then adds capacity to the existing transformer bank to match the predicted load increase.Two-phase systems are archaic and are unlikely to be encountered, these days. They are provided by alternators with two armature windings, displaced by 90 degrees.
