3-phase power supply is a rarity in residential (home) electricity. Utility companies will supply 3-phase power to farming operations, upon request and payment, at least in North America. This kind of electrical power is normally supplied to industrial enterprises.
When a properly wired 3-phase electrical machine is disconnected from its (typically 480 Volt) electrical power supply, the following results should occur:
Any and all machine motion stops, or begins to coast down to a quick stop.
Industrial robots within the machine suffer a "hard stop." Their drive motors lose power and their spring-loaded brakes (held off by electrical power) slam on.
Air pressure to the machine is cut off and residual pressure is exhausted by a safety air valve.
Hydraulic pumps lose power and stop supplying fluid pressure.
Various cylinders may relax under the force of gravity, which cannot be turned off, and cause a short-lived residual motion.
All safety systems will be disabled, and all indicator lamps will go off.
Capacitors in the electrical system may still retain voltages dangerous to operator safety, especially if they are not equipped with "bleeder" resistors.
Any control panel may contain multiple electrical power sources within, hopefully designated by yellow wires, and not be killed by the disconnect.
There is no safety system that can negate the weight due to gravity.
With no three phase power supply you can't use a three phase motor of any kind at all!
You don't. A three phase motor will not start unless it is connected to a three phase supply.
Bcoz in single phase if supply is interrupt or any trouble there is no power .but in 3 phase if 1phase supply gone we can manage it by other 2 phases
A single phase supply can operate a three phase motor with a static converter. No a power supply of computer cannot be fed through the static converter.
The power supplied by a three-phase supply, or any supply come to that, is determined by the LOAD, and not by the supply. So you must look at the data provided on the equipment's nameplate to find out what its power rating is.
Yes of course!! 10 kva electrical power is 10 kva electrical power either it would be three phase or single phase. But other factors i.e. current, voltage changes accordingly. Actually this question is quit confusable. Because in 3phase system, if each phase gives 10kva power (single phase power = 10 kva) then 3 phase power will be 10 X 3 = 30 Kva If we go leteratualy towasrds the question, then the asnwer will be - No. becasue 10 kva supply to 3 phase load will be 3phase supply(i.e440V) & 10kva supply to single phase load will be single supply (i.e 250V).

No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
You can get a 3-phase supply in most properties by negotiation with the power company, if your demand for electric power is high enough.
yes
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.
3 Phase power is supplied by a 3 pole supply like a breaker. So essentially yes.
