It varies by location and application. I will assume for this answer that we are talking low voltage (<1000 VAC): Grounded Wye Systems: 208/120 (Common) 480/277 (Common) 600/347 (Rare) Delta: 480 (ungrounded) 240/120 (grounded high-leg) 480/480 (corner grounded- rare and dangerous) The convention used above i.e. 208/120 designates the phase-phase voltage (208) and the phase to ground voltage (120). Some of the common Medium Voltage systems: 4.16 kV, 7.2 kV, 12.47 kV, 13.8kV
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
The three phase voltage is 380 the hertz is 50
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.
Let's get the terminology correct. A 'phase voltage' is measured across a phase, whereas a line voltage is measured between two lines. So there is no such thing as a 'phase to phase' voltage -it's a line to line voltage (hence the term 'line voltage').
The single phase voltage in India is 230v when we check with the phase and the nutral single line
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.

Phase to Phase voltageCorrection to the above answer:There is no such thing as a 'phase-to-phase' or 'phase-to-ground' voltage. The correct terms are 'line-to-line' (or 'line voltage') and 'line-to-ground' (or 'phase voltage'). Transmission-line voltages are line-to-line (or 'line') voltages.

The formula you are looking for is - phase voltage/1.73 = phase to neutral voltage.
By 'volts per phase', I assume you mean 'phase voltage' as opposed to 'line voltage'?It depends on the country in which you live. In North America, for example, the secondary output of a three-phase distribution transformer typically delta connected, 240 V corresponds to both the phase and line voltages.In other countries, where a three-phase distribution transformer's secondary is wye connected, 240 V is typically a phase voltage and 415 V is a line voltage.
The voltage in a three phase delta system is stated by the phase to phase voltage. If it is a wye connection the phase to neutral is represented by the two voltages. e.g. 120/208, 240/415, 277/480, 347/600, 7225/12500, etc.
Pakistan has a 220 v 50 Hz domestic supply and the three-phase voltage is sqrt(3) times higher, or 381 v. Higher voltage are also used for three-phase power transmission.
In a three-phase system, the voltage is measured between any two of the three phase conductors. The voltage between two phases in a 3-phase system is higher at 440v compared to a single-phase system where the voltage is measured between one phase and a neutral wire, resulting in 230v. The higher voltage in three-phase systems allows for more power to be transmitted efficiently over long distances.
