No, a 230V supply is normally single phase, 50 Hz. It is the most common supply used in homes and offices in Europe and many other areas of the world.

In Europe, low voltage is distributed as three-phase, four-wire, supply system having a nominal line voltage of 400 V (line-to-line) and a nominal phase voltage of 230 V (line-to-neutral). So, yes, you could describe 230 V as being a 'three-phase' voltage.
Most residences are provided with a single-phase supply, which means that each home is connected between one of the three line conductors and the neutral conductor of a three-phase system. In some European countries, such as Cyprus, it is common for residences to have three-phase supplies, with the various circuits within the home being roughly-evenly distributed between each of the three lines and the neutral.
The process of obtaining 220 volts from 380 volts is quite simple. 380 volts is a three phase four wire system voltage. The 220 volts is obtained by taking the sq. root of 3 which equals 1.73 and dividing it into the phase voltage. 380/1.73 = 220 volts. This holds true with any three phase four wire voltage system. 208/1.73 = 120 volts, 415/1.73 = 230 volts, 480/1.73 = 277 volts and 600/1.73 = 347 volts. This lower voltage is present on any of the three phase legs of the three phase system to the neutral which is grounded on a wye connection.
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
Yes, just use L1 and L2 ( just 2 of the 3 legs), or one of the legs to a neutral wire if equipped. Just make sure the voltage is the same as the 220 volts you wish to have with single phase service.
Answer 1: TV's use single-phase power. Answer 2: TV's use single phase power of 220 or 110 volts ac power depending on what part of the world you live in.
No.
220 volts.
A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.

The standard units were 220 volt, 3 phase. 220 single phase was a purchase option. There were also conversion kits to convert the machines from 3 phase to single phase. The kits contained a 1 HP 220 volt capacitor start motor and a DC motor brake control assembly. Jerry S greentron@att.net

Nothing happens. This is a normal way to obtain a single phase system from a three phase system.
If you have a voltage of 127 volts to neutral (ground) then your wye connected three phase leg voltages will have to be 127 x 1.73 = 220 volts. This voltage is within the 10% allowance for voltages as should operate the compressor. As the voltage is lower that specified, the amperage rating when a reading is taken will be higher than that of the equipments nameplate.
