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.
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.
The three phase voltage is 380 the hertz is 50
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
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.
The formula you are looking for is - phase voltage/1.73 = phase to neutral voltage.
The single phase voltage in India is 230v when we check with the phase and the nutral single line
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').
In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases, or balanced). But don't get available current and available power confused (KVA is not the same as KW).
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.
The formula to use is, phase voltage /1.73 = phase to neutral (ground) voltage.CommentThere is no such thing as a 'phase to phase', or 'phase to neutral' voltage. The correct terms are 'line to line' and 'line to neutral'. So the above answer should read: line voltage/1.73= line to neutral voltage = phase voltage.
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.
It is 230V single phase and 440V in 3 phase system at 50 Hz.AnswerIf the single-phase voltage is 230 V, then the three-phase voltage must be 400 V, not 440 V. The line voltage is 1.732 times the phase voltage.
