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

∙ 11y agoThese are the most common systems.
In the United States the three phase voltage systems are 120/208 and 480/277 on the low voltage secondary side. Primary side high voltage 7200/12470.
In Canada the three phase voltage systems are 120/208, 480/277 and 347/600 on the low voltage secondary side. Primary side high voltage 7200/12470
On the primary side both voltage systems are the same due to the fact that both countries are connected to the North American gird.

What is 3 phase voltage in Iran?
The three phase voltage is 380 the hertz is 50
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 three phase line current convert in single phase?
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.
What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
How do you calculate 440v phase?
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').
What is 3 phase voltage in Germany?
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.
What is 3 phase voltage in Iran?
The three phase voltage is 380 the hertz is 50
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 three phase line current convert in single phase?
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.
How do you calculate low phase voltage of a three phase four wire system without using voltmeter?
The formula you are looking for is - phase voltage/1.73 = phase to neutral voltage.
What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
How do you calculate 440v phase?
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').
When you have 56KVA available in 3 phase supply how much is your available current in 3 phase and how much in 1 phase?
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).
Is the voltage in a three-phase system stated by the phase-to-phase or phase-to-ground voltage e.g. 500kV or 290kV?
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.
What are the volts per phase on a 240 volt system?
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.
What is the three phase voltage in Pakistan?
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.
If in the three phase connection phase to phase voltage is 400v what will be the phase neutral voltage?
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.
