There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.

Is 10 kva supply to 3 phase load is equal to 10kva supply to single phase load?

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).


On a vessal On a three phase 440v supply what is the voltage on the individulal phases?

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.


How capacitor and resitor in a circuit effect the phase of input voltage?

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'.


Can you run a three phase appliance on 240 volt power supply?

No. You need a 3-phase supply that matches the voltage and current rating of your appliance.


Vlotage on motor name plate is line or phase voltage?

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.

How do connect no of 1phase lamp series connection in 3phase?

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.


How can I use 380v 3 phase to power 220v 3phase motor?

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.


What is typical single phase voltage in Canada?

The standard nominal voltage in Canada for a single-phase residential supply is 240/120-V split-phase supply.


What is the phase voltage inside a motor if one phase is lost and what is the voltage between the other two phases?

The phase voltage is usually constant and determined by the supply voltage.


Can i run single phase dc motor from 3phase bldc controller. i m using single phase motor in motorcycle and controller from other electric vehicle. if yes please tell me how to connect it?

It is possible to run a DC motor on a 3-phase supply using a full-wave rectifier if the voltage is right.


What is the voltage and current for a single phase supply?

240v


How you can convert 1-phase voltage to 3-phase voltage and vice-vars a?

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.


HOW and Why there is 440v supply in three phase and 230v supply in single phase?

because all over the world there is an standard rate of voltage


How many amps will a 50KVA 3phase bank carry on 277 - 480 volts?

50 kVA is 16.667 kVA per phase and you divide that by the phase voltage. Current = 16667 / 277 = 60 Amps


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.
