How the single phase load works on same voltage- two phase supply?

Two-phase supplies are very unusual these days, and describe an a.c. system in which the two phase voltages are displaced by 90 degrees. So you are probably thinking of a split-phasesystem.
A split-phase system is created using a transformer with a centre-tapped secondary winding. The centre tap is grounded (earthed) and provides the neutral terminal. The outer terminals (labelled X1 and X2) supply a potential difference of 240 V between them, while terminals X1 to neutral and X2 to neutral each supply potential differences of 120V.

Can you change the wiring of a single phase appliance of 2.4 kw that works on 240 to 400 volts 3 phase 60 hz supply?
No, you can not you change the wiring of a single phase appliance of 2.4 kw that works on 240 to 400 volts 3 phase 60 Hz supply. They are two different electrical systems.
Is air conditioner works on 1 phase and how it works on 3 phase also?
If an air condition is single phase, then it can only be connected to a single phase source. Since any two legs of a three phase source are considered single phase, there is no conflict, except to note that the individual phases of the three phase source match the voltage requirement of the air conditioner.
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 is a 380v 3-phase machine to a 208v simple phase outlet possible?
if you wound 3-phase on primary of transformer and secondary side we have to only one cable only such a way that it works as a step down transformer.AnswerYou cannot run a three-phase machine directly from a single-phase (which is what I assume you mean) supply. It won't start. The voltage difference is irrelevant.
How convert 1 phase to 3phase in aircraft?
The power is generated in the form of three-phase in aircraft, and this sytem has no problem in feeding single phase loads. To conserve mass in tansformers and motors the supply works at 400 Hz.
What voltage mercury lamp works?
the supply voltage to a mercury vapour lamp (from the electromagnetic ballast) is 130vac
What are the phase voltages if the line voltages are 100volts?
It depends on the type of three-phase system. If it's a three-wire system, then the phase voltage is numerically equal to the line voltage. If it's a four-wire system, then the phase voltage is numerically equal to the line voltage divided by 1.732 -in your example, this works out to be 5.77 V.
What is termination voltage in DDR3 RDIMM?
DDR3 works with 1.5V supply,so it needs a termination voltage half of it i.e 0.75V LDDR3 works with 1.2V supply,so it needs a termination voltage half of it i.e 0.6V Sukumar Reddy.P
Why when voltage applied to only one phase of the primary side voltage is produced in all the three phases of secondary in a transformer?
Your question doesn't describe under what circumstances the transformer is being used. Normally, a two wire (hot and ground) AC voltage can only be a single phase supply. Look up the explanation of how AC current cycles on a sinewave (60Hz is 60 sinewave cycles per second). This is also known as a single phase. Coming into a standard residential house is a three wire line with two hot wires and a ground wire. The two hot wires are out of phase with each other (opposite sinewave). A standard transformer can have multiple outputs with various/same voltage. Look up how a transformer works. Without special electronic components for each output circuit, all taps will be in phase. A transformer outfitted with the special electronic components is very expensive and not for normal everyday use.
What is construction and working of single phase transformer?
The single phase transformer works on the principle of mutual induction. Explanation: When an alternating voltage V1 is applied to a primary winding, an an alternating current I1 flows in it producing an alternating flux in the core. As per Faraday's law of electromagnetic induction, an emf e1 is induced in the primary winding. Where N1 is the number of the turns in the primary winding's induced emf in the primary winding is nearly equal and opposite to the applied voltage V1
What are then line and phase voltage for a 415v 50Hz balanced delta connected system which has a load consisting of 100 resistance and 200mH inductance?
If it has one load, it isn't balanced.AnswerThe voltages are determined by the supply, not by the load -so they would remain at 415 V (line voltage) and 240 V (phase voltage) regardless of your load. But, assuming your load specification is per phase, then you have a balanced load and the phase and line currents are easily calculated.The first step is to determine the impedance per phase, which is the vector sum of the resistance and reactance -the reactance can be calculated from the inductance value (63 ohms) -this works out at 118 ohms.Next, we find the phase current, which is the phase voltage (240 V) divided by the phase impedance, 240/118 = 2 A. Finally, we calculate the line current, which is 1.732 times the phase current = 3.5 A.
How do you convert a 3-phase power supply to a single phase supply?
The simplest answer is that the electric utility uses a transformer across 2 of the 3 hot leads to develop a single hot lead with an earth reference. What follows below is frequently edited by both amateurs and professionals, with mixed results. Wikipedia is a better source of more detailed information on this subject, in part because the article on three phase power has pictures.
