A single-phase supply is obtained between any two line conductors or between a line and neutral conductor of a three-phase supply. To obtain a three-phase supply from a single-phase source is far more difficult, and requires additional equipment.
It is not advisable to run lower voltage motor on a higher voltage.
because 3Phase power - V X I X Cos Phi X Square root of 3 and square root of 3 - 1.73
bcoz we dont require too much voltage when working in home so in home generally 220v is preferred & in industries 3phase connection is used for heavy loads (440v)
A 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 350 amps for 150 feet on a 208 volt system.
It would happen in case of 3phase domestic use where consumer side load balancing is not being done and there is loose connection in the neutral wire. Due to the unbalance and poor neutral, the system neutral will be shifted and un balanced voltages will be recorded in all the 3 phases of the house. The phase loaded with much utilities will indicate less voltage and other will have high voltage. Gadgets connected to this phase will be damaged.
depending on 1phase or 3phase voltage motor , the amphere requirement is found outfor 3phase AC motor use this formula: (HP x 746)/(1.73 x E x Eff x PF)for 1phase AC motor : (HP x 746) / (E x Eff x PF)
Just use 2 of the wires instead of 3.
Into units of what?
Yes it can run when single phasing in a delta configuration but the motor will not start from a dead stop. There will be quite a bit of degradation in its operation from its nameplate data.
It is not advisable to run lower voltage motor on a higher voltage.
This is a voltage drop question. A voltage must be stated to answer this question.
A frequency converter converts alternating current of one frequency to alternating current of another frequency. Generally it's used for controlling the ac motor speed by changing the supply frequency.
Generator coils generate the voltage, motor coils use the generated voltage.
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
Ohm's Law - V = IR.
Your question is not clear. Are you asking how you can obtain a single-phase supply from a three-phase system? If so, then it depends on the type of three-phase supply and the voltage you require. For example, a three-phase, three-wire, system, single phase is obtained between any two line conductors. For a three-phase, four-wire, system, single phase is obtained either between any two line conductors, or between any line conductor and the neutral conductor. In the case of the latter, two voltages are available, a line voltage and a phase voltage, with the line voltage being 1.732 x larger than the phase voltage.
It is very unlikely that you will ever come across an archaic 'two-phase' system, so your question is of academic interest only. A two-phase, three-wire, system is one in which phase voltages are generated 90 electrical degrees apart and whose line voltage is, therefore, 1.414 greater than its phase voltage. So, the answer to your question is no.
