Neutral is a return path.
A three phase delta system does not use a neutral in its operation.
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
You can connect a single-phase load between any one of the three lines and neutral. But it is potentially a dangerous operation if you don't know what you are doing so speak to an electrician who will ask the right questions to find out exactly what you want.
Yes there is single phase for 600 volts. It is used for lighting. You need a transformer which gives you 600 volts plus a neutral. The voltage for the one phase to neutral is 347.
You can divide a three phase service into (3) single phase circuits providing you have a 4th neutral wire.
yes we can by using one phase and neutral line
The neutral in single phase AC circuits is used as the common power return conductor for half phase operation. In a typical (US/Canada) 120/240 split phase system, generally used in residential applications, the voltage between neutral and either of the two hot conductors is 120 VAC, and the voltage between the two hot conductors is 240 VAC. Neutral is also grounded at the distribution panel, as well as at the utility distribution transformer, in order to limit the voltage of any conductor relative to ground, and also to be able to detect ground faults by sensing imbalance between neutral and hot currents. Note that this is not called two phase power. It is single phase, or split phase, and it comes from one center tapped transformer winding. The center tap is neutral.
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
A single phase supply can be obtained between any pair of line conductors or between a line conductor and a neutral conductor.
yes
The current is the same in the three live wires. The voltage can be described as the line voltage (phase to neutral) or the phase voltage (phase to phase) which is larger by a factor of sqrt(3). So a line voltage of 230 v corresponds to a phase voltage of 400 v.
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.
