Three phase power is always delivering power on one of the phase continuously. This is very useful to manufacturing industries to operate the machines, which require high power utilization.

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.
With no three phase power supply you can't use a three phase motor of any kind at all!
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.
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.
You don't. A three phase motor will not start unless it is connected to a three phase supply.
To use a single-phase motor in place of a three-phase motor, you would typically need a phase converter to convert the single-phase power supply into three-phase power. Alternatively, you can replace the entire motor with a single-phase motor that has similar specifications as the three-phase motor. It's important to consult with an electrician or engineer to ensure compatibility and safety.
No. A three-phase ballast requires three-phase power
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 commonly used in industrial and high-power applications because it is more efficient and has a higher power output compared to single-phase power. It also provides a more balanced power supply and reduces the stress on electrical equipment. Additionally, three-phase power allows for smaller size conductors and motors for the same amount of power provided by single-phase power.
In Europe, AC power is typically supplied as single phase for residential and small commercial buildings. Larger commercial and industrial properties may receive three-phase power.
Single phase supply alternates like a sign wave, from negative to positive, producing a less reliable source of power, where as three phase is effectively three lots of single phase source, within the time of a standard single phase source. Each of the three phase sources are 120 degrees out of phase, producing a more consistent power source which can carry greater loads.
