Phase voltage is determined by the wiring of transformer that serves the building. To test phase voltage use a volt meter and put one probe to ground and the other to each phase and observe the reading, this will give you a phase to ground voltage reading. Next test phase to phase (1 to 2, 1 to 3, and 2 to 3) to see if it's 208, 240, 277, or 480. Only licensed electricians should perform these tests. DAW

What is the total of a phase to earth voltage on 11000 volts?
An 11,000 volt three-phase supply has a voltage of 6351 from live to neutral, when there is a neutral wire.
HOW and Why there is 440v supply in three phase and 230v supply in single phase?
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.
What are the phase voltages if the line voltages are 100volts?
It depends on the type of three-phase system. If it's a three-wire system, then the phase voltage is numerically equal to the line voltage. If it's a four-wire system, then the phase voltage is numerically equal to the line voltage divided by 1.732 -in your example, this works out to be 5.77 V.
How do you get 347V?
347V can be obtained from a three-phase power system, where the phase-to-phase voltage is 347V. This typically involves connecting three alternating current power lines that are 120 degrees out of phase with each other to create a three-phase circuit, which results in a higher voltage output than a single-phase system.
Is transmission voltage a phase to phase voltage or a phase to ground voltage?
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.
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.
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').
How do you calculate New Zealand 3 Phase Voltage?
To calculate the three-phase voltage in New Zealand, you typically use the formula for line-to-line voltage (V_L) in a three-phase system, which is V_L = √3 × V_Ph, where V_Ph is the line-to-neutral voltage. In New Zealand, the standard line-to-neutral voltage is 230V, so the line-to-line voltage would be approximately 400V (230V × √3). Ensure that the system's configuration (such as star or delta) is taken into account when performing calculations.
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.
What is the total of a phase to earth voltage on 11000 volts?
An 11,000 volt three-phase supply has a voltage of 6351 from live to neutral, when there is a neutral wire.
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.
HOW and Why there is 440v supply in three phase and 230v supply in single phase?

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.
Three phase voltage in india?
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.
What are the phase voltages if the line voltages are 100volts?
It depends on the type of three-phase system. If it's a three-wire system, then the phase voltage is numerically equal to the line voltage. If it's a four-wire system, then the phase voltage is numerically equal to the line voltage divided by 1.732 -in your example, this works out to be 5.77 V.

How much voltage in three phase line in electric in India. each phase rating 230V?
If the phase voltage is 230 V, then (providing you are describing a three-phase, four-wire, system), then the line voltage will be 1.732 larger -i.e. 400 V.
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.
