The power circuit is only active between two phases - the live and neutral. Thwe third phase (Earth) is simply a safety device designed to blow a fuse in case of short-circuit. The power is delivered down the live wire, and returned by the neutral to complete the circuit.

What is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
How does a two-phase system differ from a three phase system?
A two-phase system is archaic and you are unlikely to find it in use anywhere these days, so it is mainly of historical interest. A two-phase, three-wire system, consists of two phase voltages, displaced from each other by 90 electrical degrees, and a phase voltage which is 1.414 x phase voltage.A three-phase system consists of three phase voltages which are displaced from each other by 120 electrical degrees. In the case of a three-phase, three-wire, system, the line voltages are numerically equal to the phase voltages; in the case of a three-phase, four-wire, system, the line voltages are 1.732 x phase voltage.
How many voltage 3phase line?
For a three-phase, three-wire, system there are three conductors called 'line conductors', and there is a voltage between any pair of line conductors, so there are three voltages.For a three-phase, four-wire, system there are four conductors: three 'line conductors' and a 'neutral' conductor. So there are three line voltages (voltages between lines) and three phase voltages (voltages between any line conductor and a neutral conductor).
What would be the 3 phase voltage on a frequency of 50 Hz?
Single phase and three phase voltages are not related to the frequency at which the voltage is generated. The frequency at which voltages are generated is governed by the speed of rotation of the generating device.
What is the Difference between single phase current and three phase current?
given a balance three phase, three wires system with star-connected load for which lime voltage is 230v and the impedance of each phase is (6+j8)ohm. find the line current and power absorbed by each phase.

How many volt each phase in three phase?
600 volts between any two wires. The phase has nothing to do with voltages, only current relationship.
What are the equations to get KVA?
If using L-L voltages, the three phase power = V*I*sqrt(3)If using L-N voltages, the single phase power = V*ITo convert single phase to three phase, multiply by 3.

How are single phase and 3 phase voltages generated?
One hamster vs. three hamsters.
Line to line voltage?
The conductors between a three-phase supply and a three-phase load are called line conductors not phase conductors, and the voltage measured between them are line voltages, not phase voltages. In the case of a delta supply, the line voltages are numerically equal to phase voltages, but the name remains the same!I have to admit that many people call line conductors 'phase conductors', but many people also say 'irregardless' -that doesn't make it a real word!!
How do you calculate the resultant 3 Phase voltage when each has a different reading close to 230?
Your question is not clear.There is no such thing as a 'resultant' three-phase voltage. There are three, separate, line voltages (i.e. voltages measured between line conductors) for a delta-connected supply, which are equal in magnitude to the corresponding phase voltages. For a balanced wye-connected system, there are three line-voltages (again, measured between line conductors) which are 1.732 larger than the three phase-voltages (measured between each line conductor and the neutral conductor). For an unearthed unbalanced three-phase wye-connected load (unusual, but possible), the figure of 1.732 doesn't apply; instead the relationship must be determined by vector addition.If your question means to ask how do you determine the line voltages of a wye-connected system, given a set of unbalanced phase voltages, then you must vectorially add the relevant phase voltages to determine the relevant line voltage, taking into account the sense, or direction, of each phase voltage.
Does the formula used to calculate the turns ratio uses the phase voltages and phase current?
For a transformer, the turns ratio always applies between its primary and secondary windings. So the turns ratio for a three-phase transformer is the ratio of primary to secondary phase voltages, not between line voltages.
What would be the 3 phase voltage on a frequency of 50 Hz?
Single phase and three phase voltages are not related to the frequency at which the voltage is generated. The frequency at which voltages are generated is governed by the speed of rotation of the generating device.
What is the voltage of other two phase of 3 phase system when One phase is open?
If you mean 'phases' and not 'lines', then the loss of a phase has no effect on the voltages provided. You will still obtain three voltages, displaced from each other by 120 degrees.
What is the Difference between single phase current and three phase current?
given a balance three phase, three wires system with star-connected load for which lime voltage is 230v and the impedance of each phase is (6+j8)ohm. find the line current and power absorbed by each phase.
