It is the square root of 3. Multiply 1.732 to 120v. and you get 208. which, on a three phase system, is the voltage from line to ground.

Does kva equal voltage x current x 1.73 for a 3 phase generator?

Yes, but only for balanced loads (current in all three phases the same value). The voltage value used is the phase to phase voltage.


How do you get phase voltage from 3 phase 3 wire line?

If the three legs of a three phase source are A, B, and C, then you can connect them in delta configuration as AB, BC, and CA to get the three phases.If the three legs are properly balanced, and you have a neutral/ground leg N, then you can connect them wye configuration as AN, BN, and CN to get the three phases.AnswerWith a three-phase, three-wire, system supplying a deltaconnection, the phase voltages are numerically equal to the line voltages.A three-wire system's load can also be connected in wye(star), in which case you will obtain the phase voltages between any one line and the neutral or star point of the load connection. In this case, providing the load is balanced (i.e. identical in all respects) the phase voltage will be 0.577 times the value of the line voltage.


Why delta connection is used in load side?

There are a number of advantages why three phase (delta or Y configuration) is preferred over single phase circuit. The best advantage is that the each of the three lines in a three phase circuit can act as single phase thus effectively getting three single phase circuits in one transmission. Another advantage is whether it's single phase or three phase, the generation is the same, therefore three phase has more practical value. Also, the instantaneous power in single phase falls to zero but in three phase system, the net power from all the phases is continuous.


What is three-phase unbalanced load?

A balanced three phase load is where the current flowing in all three phases of the load are reasonably close to each other.Another answerWhen the voltage and measured current draw do not deviate by more than 2 percent under load.AnswerA balanced three-phase load is one in which each of the three loads is identical in all respects (magnitude and phase). Further to the first answer, the three line currents must not all be 'reasonably close', they must be identical -i.e. the same value and phase relationship.

How you convert the value of single phase power to value of 3 phase power?

Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.

You can't. Currents in three-phase systems are measured in each of the individual line conductors.

Yes, but only for balanced loads (current in all three phases the same value). The voltage value used is the phase to phase voltage.

How do you convert 380v 3 phase to 220v 3 phase?

Mathematically, just divide 480 by the square root of three. Electrically, 480V refers to the line-to-line value of a three phase system. For example, measure the voltage across A-phase and B-phase and you'll get 480V. 277V is the line-to-neutral value. Measure the voltage across A-phase and the neutral conductor and you should get 277V.

Why floating neutral in a three phase supply is undesirable?

Floating neutral in 3 phase supply is undesirable as if the same thing occurs then there will be bad effect for all single phase equipment which we are using as phase to neutral voltage will exceed from its normal value and it will harm the equipments.


What is the difference between the voltages in the coils A and B in three phase generator?

I assume that you are referring to phase A and phase B? So what happened to phase C, in that case? The answer is that the magnitudes are the same, but phase B (and phase C) are displaced by 120o. The normal phase sequence (the order in which each voltage would reach its peak value) would be A-B-C.
