KV is the abbreviation for kilovolts. The prefix kilo means thousands, so 220 kv means 220 kilovolts, or 220,000 volts.
With no three phase power supply you can't use a three phase motor of any kind at all!
All a.c. transmission systems are three-phase systems, which comprise three line conductors which are suspended from towers. Each 'line' is generally made up of a number of 'bundled' conductors -according to the transmission voltage- to reduce the electrical stress. Many transmission towers carry two separate three-phase circuits, one on each side of the tower.
Polyphase systems are used because they allow the efficient transmission of electric power, in terms of power transmitted per kilogram of wire. Polyphase systems with more than three phases are very uncommon.
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
Houses generally run on single phase power. It would not make sense to convert single phase to three phase to run a house. Please restate the question.
Three phase power is a method of electric power transmission using three wires. Three phase power systems may have a neutral wire that allows the system to use a higher voltage while still allowing lower voltage single phase appliances. In high voltage distributions, it is not common to have a neutral wire, as the loads can simply be connected between phases.
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.
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.
Power is generated in three phases because it allows for the generation of a more constant and smooth flow of power compared to a single-phase system. Three-phase power also allows for greater efficiency and power transmission over long distances.
The basic difference is the secondary voltages. On a distribution transformer the secondary voltage is very high. This is to overcome line loss for transmission of electricity over long distances. A three phase power transformer is used at the consumers three phase services end to manipulate voltages that consumers need to operate their equipment. The transformer that feeds your house is considered to be a single phase power transformer.

You need three phase power to get three phase power. If you only have one phase, you will need some kind of inverter or motor-generator set. Generally, however, the demands of a three phase motor will exceed the capability and efficiency of these "tricky" solutions. It is best to simply contact your local power company and have them provide the proper three phase power to your facility.
You will need to determine the power per phase, and add them up to give the total power of the three-phase load. To do this, you will need to multiply the phase-voltage by the phase current by the power factor -for each phase.

You don't. A three phase motor will not start unless it is connected to a three phase supply.
