You can ask your local utility. They may or may not tell you, depending on how high of voltage you're talking about, and whether sharing this information opening is deemed a security risk (even though you might be able to walk around and see them).
The line-to-neutral (not 'phase-to-neutral'!) voltage on a 400V 3-Phase wye-connected system is 230V.Line voltage is the voltage as measured between any two (2) line conductors (hence its name!). Line voltage is often referred to as the 'line-to-line voltage'.Phase voltage is the voltage as measured between any single line and neutral. Phase voltage is often referred to as a 'line-to-neutral' voltage."400V" on a 400V 3-Phase wye-connected power supply indicates its line voltage. Line voltage in a wye system is always the phase voltage multiplied by the square-root of "3" (1.732) and reflects the vector sum of two individual phase voltages present in a three phase system.Thusly, if the line voltage is "400V", then the phase voltage is 400V divided by the square-root of "3" (1.732), which is 230V.Examples of this for North American power systems are 120/208V, 277/480V and 347/600V. Examples for other areas of the world are 220/380V, 230/400V and 240/415V.
The energy supplied by a power line is determined by its load, not by its voltage. For a given energy demand by its load, the higher the liine's voltage, the lower the resulting load current.
The power factor for a three phase generator is 80 percent. The generator consumes 36 kilowatts and a line to line voltage of 400 volts.
A lamp can be run by power from a telephone line.
In Europe, low-voltage three-phase distribution is by means of a four-wire system (three line conductors and a neutral) supplied from a wye-connected transformer secondary. In North America, low-voltage is supplied from a delta-connected transformer secondary, one phase of which is centre-tapped and earthed (grounded). The single-phase supply to residences is then supplied by that particular phase, giving 240 V line-to-line and 120 V line-to-neutral. You can tell if you have a delta power when the phase voltage is equal to the line voltage and that you have a star power when the phase voltage =root 3(THE LINE VOLTAGE).
With a three-phase system the voltage quoted is the line-to-line voltage between any two live lines. To find the line-to-neutral voltage divide by 1.732 which is sqrt(3). The power supplied from each phase is the current times the line-to-neutral voltage (times the power factor if less than 1). To find the total power when the currents are equal, multiply by 3.
Phase, if you are referring to line, as power line from pole.
The voltage present in a power grid line is more than enough to kill you.
Line regulation is a measure of the ability of the power supply to maintain its output voltage given changes in the input line voltage. Line regulation is expressed as percent of change in the output voltage relative to the change in the input line voltage.

You can find the power rating of your power supply by looking at the label or sticker on the unit itself. It should indicate the maximum power output in watts (W). You can also check the manufacturer's website or product manual for this information.

For a line of given cross section and material, the power capacity will depend on the current carried, since resistance heating is proportional to (current)2 . For a given power, current is inversely proportional to voltage. Thus raising the voltage from 69 to 390 kv would reduce the current by a factor 69/390 = 0.177 , for the same power transmission, and reduce the heating losses by 0.1772 = 0.031. So you can see why high voltage for long distance lines is essential. Obviously the limiting current on a power line has to be set by economic and practical considerations, but if this is predetermined and set, the limiting power will be that which produces that limiting current, and power = voltage x current. The actual limiting curent will depend on the line cross section, material, and length. The power that a line of a certain voltage can carry is calculated by using the following formula: (2.55×(KV)2 /1000) MW.
The power factor for a three phase generator is 80 percent. The generator consumes 36 kilowatts and a line to line voltage of 400 volts.
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.
