Symmetrical components are a good way to represent out-of balance currents in 3-phase power supplies.
In general an unbalanced set of currents in a 3-phase system can be represented by three compents, which are an in-sequence component, an out-of-sequence (rotating oppositely) component, and a zero-sequence component.
At a high-power substation there would be meters for all three components of the current. When the currents are perfectly balanced only the positive sequence current would be non-zero.

What cannot be considered a single phase?
Any load that needs three legs from a three phase system can not be considered single phase. Single phase from a three phase system only needs a connection to two legs.
What is kando system?
it convert the single phase in to three phase.
How many volt each phase in three phase?
600 volts between any two wires. The phase has nothing to do with voltages, only current relationship.
Is a three phase three wire system safe?
Three-wire transmission is used on balanced three-phase systems when the current is known to be equal in all three phases, for example when supplying a three-phase motor. A fourth neutral wire is used when the system is liable to have unequal currents or when multiple single-phase supplies are connected to it.
How many wires are in a 3 phase circuit?
A ground, or earth, conductor is never included in the conductor count. So, a three-phase, three-wire, system has three line conductors, whereas a three-phase, four-wire system, has three line conductors and a neutral conductor.
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".
How does a two-phase system differ from a three phase system?
A two-phase system is archaic and you are unlikely to find it in use anywhere these days, so it is mainly of historical interest. A two-phase, three-wire system, consists of two phase voltages, displaced from each other by 90 electrical degrees, and a phase voltage which is 1.414 x phase voltage.A three-phase system consists of three phase voltages which are displaced from each other by 120 electrical degrees. In the case of a three-phase, three-wire, system, the line voltages are numerically equal to the phase voltages; in the case of a three-phase, four-wire, system, the line voltages are 1.732 x phase voltage.
What cannot be considered a single phase?
Any load that needs three legs from a three phase system can not be considered single phase. Single phase from a three phase system only needs a connection to two legs.
What is a balanced three phase system?
A balanced three phase system is where the currents into the loads placed on all three phases of the service are reasonably close to each other in amperage.Another opinionA 'balanced' three-phase system describes a three-phase load in which each phase current is identical in both magnitude and phase. If the phase currents are only 'reasonably close', then the load is not balanced.

What is kando system?
it convert the single phase in to three phase.
What is the purpose of a phase conductor?
There is no such thing as a 'phase conductor'; the correct term is 'line conductor'. In a single-phase system, the line conductor is the energised conductor; in a three-phase system, there are three (energised) line conductors.
What are the uses of three phase transformer over single phase and their losses?
For a given load, a three-phase system requires around 75% of the volume of copper required by a corresponding single-phase system and, so, is more economical. A three-phase supply also delivers power more or less continuously, whereas a single-phase supply delivers power in pulses. Finally, three-phase motors are self-starting and physically smaller than single-phase machines of the same power rating.
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 is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
How many volt each phase in three phase?
600 volts between any two wires. The phase has nothing to do with voltages, only current relationship.
What is this system called with three single phase transformer?
Your question is rather vague. If you are asking what do you call a group of single-phase transformers, connected to supply three phase, then the answer is a 'three-phase transformer bank'.
