What are the advantages of using a three-phase system over a single phase system?
For the info. of everybody..... the 3-phase system is definitely use in large commercial & industrial plant that uses large equipment/apparatus, like motors powered by more than 230v supply. However, single-phase system was commonly used in residential, which uses 230V or 110V equipment/apparatus, also considered as light load....

In a three phase power system the phases of each voltages are normally separated by how many time degrees?
In a three phase power system, each phase is separated from the others by 120 degrees.
What significance has a power factor in an unbalanced system?
A three-phase 'unbalanced' system refers to the load, as the supply voltages are unaffected by load. So the phase-angle and, therefore, the power factor of each phase will be different -i.e. there will be three different power factors.
In a modern industrial plant the most likely polyphase power system in use is a A. one-phase system. C. three-phase system. B. two-phase system. D. four-phase system.?
A "three-phase system" is a polyphase system having three phases. The term "polyphase system" just means a system having multiple phases. If it is used by itself, "a polyphase system" doesn't mean "a three-phase system".
What are some advantages of 3-phase power over 1-phase power?
There are several advantages of 3-phase power over single phase power. First, with 3-phase power, more power can be transferred with the same amount of wire (meaning the amount of copper used in all of the conductors transferring that power) as with single or 2-phase power. Also, power is transferred more "evenly" with 3-phase power because the "next peak" is closer than it is with single and 2-phase power. The 3-phase motors run more smoothly than those run on fewer phases. Also, there are motor design considerations (one being control of the direction of rotation) regarding the motor that make 3-phase power more attractive. Use the link to the Wikipedia article on 3-phase power and skim it. It isn't long and it is quite readable.

If 1 phase 240 is used to power a piece of equipment that should be powered by 3 phase 240 will it damage the equipment?
odds are it is a motor and that would be yes
Why 3 phase ac systems is preferred to 4 phase?
3 phase system has more power than a single phase system
What is the power consumption for a 3 phase of 415 volt equipment?
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.
If 3 phase 240 is used to power a piece of equipment that should be powered by 1 phase 240 will it damage the equipment?
As only one phase of a 3-phase supply can ever be properly connected to a piece of 1-phase equipment, such as a motor or whatever, no damage will result if that connection is done correctly.As most household 1-phase ac power is derived from power generated and distributed as 3-phase power, this question may just be an exam question designed to catch out students who don't really know what they are talking about...For more information please see the answer to the Related Question shown below.

Where would I find phase converter equipment being used?
Phase converter equipment can be used in a generator. They can help provide electric power. Phase converter equipment is used to run computers, pumps, etc. There is quite a bit of information online at www.phase-a-matic.com.

Why 3 phase power only?
Three phase four wire system is found to be most economical (conductor size and number of conductors) and efficient among all the available options. Hence 3 phase power system is used widely.
Does the power factor in three phase system depend on the phase sequence?
No. It depends on the inductive and capacitive reactance of the load.
