There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
Yes of course!! 10 kva electrical power is 10 kva electrical power either it would be three phase or single phase. But other factors i.e. current, voltage changes accordingly. Actually this question is quit confusable. Because in 3phase system, if each phase gives 10kva power (single phase power = 10 kva) then 3 phase power will be 10 X 3 = 30 Kva If we go leteratualy towasrds the question, then the asnwer will be - No. becasue 10 kva supply to 3 phase load will be 3phase supply(i.e440V) & 10kva supply to single phase load will be single supply (i.e 250V).
Phase voltage is equal to the line to line voltage divided by root 3 or 1.732. So 440 L-L/1.732 = 254V. Your phase voltage is 254V.
A capacitor and a resistor has no effect on the supply voltage; however, this particular load combination will cause the load current to lead the supply voltage by some angle termed the 'phase angle'.
No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
The voltage tag on a motor says 120 or 220 volt and some motors have jumpers to wire it for either one. That is the supply line voltage. The motor knows how to use that. If the plate says three phase is required then consult your electic supply Company for a three phase supply line.
It is not advisable to run lower voltage motor on a higher voltage.

Your question is not clear. Are you asking how you can obtain a single-phase supply from a three-phase system? If so, then it depends on the type of three-phase supply and the voltage you require. For example, a three-phase, three-wire, system, single phase is obtained between any two line conductors. For a three-phase, four-wire, system, single phase is obtained either between any two line conductors, or between any line conductor and the neutral conductor. In the case of the latter, two voltages are available, a line voltage and a phase voltage, with the line voltage being 1.732 x larger than the phase voltage.
f your supply is a Y connected transformer (4 wires COM) with a phase to phase voltage of 380 volts (voltage between any two of the hot wires) , utilizing a true Y connection to your load (connections of one hot lead and neutral for each phase to your load will give a voltage of 380 รท sqrt 3 = 380 รท 1.732 = 220 volts.
The standard nominal voltage in Canada for a single-phase residential supply is 240/120-V split-phase supply.
The phase voltage is usually constant and determined by the supply voltage.
It is possible to run a DC motor on a 3-phase supply using a full-wave rectifier if the voltage is right.
240v
A single-phase supply is obtained between any two line conductors or between a line and neutral conductor of a three-phase supply. To obtain a three-phase supply from a single-phase source is far more difficult, and requires additional equipment.
because all over the world there is an standard rate of voltage
50 kVA is 16.667 kVA per phase and you divide that by the phase voltage. Current = 16667 / 277 = 60 Amps
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.
