What are the Advantage of three phase motors over single phase?
A 3 phase system needs only to use 3 or 4 conductors, as against 6 conductors if it were 3, single phase conductors The amount of copper used in a 3 phase is much less than what would be needed in a single phase system carrying the same current, this reduction in copper allows for weight reduction and cost savings. The power losses in a 3 phase system are much less than in a single phase system.
What wire size for 100 amp single phase 3 wire commercial service?
2 copper
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.

What is the Phase diagram of nickel copper alloy having 50 copper and 50 nickel at temperature from 1400C to 1200C?
At 1400C Ni-50Cu alloy is in the liquid state and at 1200C it is in a single-phase solid state, having the face-centered cubic (FCC) crystallographic structure. Alojz Kajinic, Ph.D. http://www.calphad.com/
What type of wire you used in three and single phase line?
Copper or aluminum wires.
What are the advantages of poly phase over single phase?
The primary advantage is that, for a given load, a three-phase system requires less copper for tranmission/distribution than an equivalent single-phase system would require. Other advantages include the fact that three-phase machines are smaller than single-phase machines of similar rating.
What wire size for 100 amp single phase 3 wire commercial service?
2 copper
Why you cant transmit high voltage through single phase?
You can, but for a given load it's more economic, in terms of the amount of copper used, to use three-phase.
What are the advantages between 3 phase and 1 phase?
For a given load, a three-phase system uses less volume of copper (therefore is more economical) than a corresponding single-phase system, while supplying approximately-constant power. From the users' point of view, three-phase motors are self-starting and more compact than the equivalent single-phase motor.
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.
Why you use brushes for single phase induction motors?
There no brushes in an induction motor. The rotor is independent and is a short-circuited cage of parallel bars.
How do you calculate copper losses?
copper losses are power losses due to flow of current in the wires or resistances,if the resistance is R, current is I then copper losses are I2R. for a 3-phase system; copper losses are same but for a single line, total losses are 3I2R.
What is the advantage of polyphase system over single-phase system?
1) less copper cross section to conduct current2) constant power to load3) constant rotating magnetic field4) Ideal for Direction Reversing5) Current is not zero at any constant..
Is the type of wiring in most homes single-phase or three-phase?
Single phase.
