What is 230 volt 3 phase?

Answer 1

for USA, Canada and other countries running a 60 Hz supply service.

230 volt single phase refers to the two hot wires in standard house wiring but with the absence of the common return line, aka as the neutral wire.

As using only the "hot" side of phase one (120 volt) and only the "hot" side of phase two (120 volt), so that these two lines yield 240 volts in phase with each other, it is called "single phase".

This is sometime called 230 volts, "double phase" due to the two hot wires. Since both wires have the same phase, the term "double phase" is incorrect. As the two hots are balanced around the neutral point, "Split single phase" is the correct term to use.

Typical usage examples for 240 volts split single phase include: water heaters, electric clothes dryers, water pumps for wells, central and some larger window air conditioning units, air handlers, electric heating units, floor sanders, and portable arc welders.

For Europe

230 V is the standard nominal voltage for single-phase electrical services to residences in Europe. It is obtained from a wye-connected, three-phase, four-wire, 400/230-V transformer secondary, by connecting between any line conductor and the neutral conductor.

Answer 2

A two phase 230 volt circuit is actually one phase, center tapped with grounded neutral so that the voltage from each leg to neutral is 115 volts, and the voltage from leg to leg is 230 volts. It is more properly called split phase, and each of the legs are 180 degrees apart, instead of the 120 degrees normally found in true three phase power.

Answer 3

Normally 230 V is single phase system. This has two wires - one is called phase and the other one is called as neutral wire. Neutral wire provides return path where as phase wire provides supply path. In some system there is a third wire called earth wire for safety.

Answer 4

A two-phase supply is made up from two supplies on four wires, of equal voltage but in phase quadrature (i.e. 90 degrees apart in time). Two-phase is not used any more because three-phase gives more efficient power transmission.

Answer 5

Your question, as expressed, doesn't make any sense. In Europe, a 230-V supply is obtained between any one of the three line conductors and the neutral conductor of a three-phase, four-wire, system.

Answer 6

230 V is the standard nominal line-to-neutral voltage in European three-phase systems, which means that the corresponding nominal line voltage is 400 V and it is referred to as 400 V 3-phase.
