Why are there no two four five phases in an electrical circuit?

because of to reduce the conductor size. whenever you use 4or 5 phase there have 4or5 conductors so only use 3phase. these 3phase to Cary the voltage has large. We use more voltage to transmit by using HVDC system.

Why 3 phase power is used why not 6 or 12?

All Answers (13) 6 and 12 are multiples of 3. one of the advantage of 3 phase ac is that 3rd harmonic and its multiples cancels out. so going for 6 or12 phase will only lead to extra cost and maintenance in the transmission and distribution lines.

What’s the difference between 2 phase and 3 phase electrical?

Three-phase electric power requires less conductor mass for the same voltage and overall power, compared with a two-phase four-wire circuit of the same carrying capacity. Alternatively, three wires may be used, but the common conductor carries the vector sum of the phase currents, which requires a larger conductor.

Why three phase system is adopted worldwide in comparison of two-phase system discuss the advantages of three phase system?

A three-phase circuit provides greater power density than a one-phase circuit at the same amperage, keeping wiring size and costs lower. In addition, three-phase power makes it easier to balance loads, minimizing harmonic currents and the need for large neutral wires.

Why does America use split-phase?

Its primary advantage is that, for a given capacity of a distribution system, it saves conductor material over a single-ended single-phase system, while only requiring a single phase on the supply side of the distribution transformer.

Why do we use split-phase?

A split-phase power system is one with multiple (in-phase) AC voltage sources connected in series, delivering power to loads at more than one voltage, with more than two wires. They are used primarily to achieve a balance between system efficiency (low conductor currents) and safety (low load voltages).

Can you have 4 phase power?

You could make a four phase generator, with four power lines plus maybe a neutral. This was also called a two-phase system, and was used before three phase became popular. Systems with 5, 6, 7, 9, 12, and 15 phases have been designed, and some have been built.

Why can’t we have 4 or 5 or six phase why only three?

3 phase power generating and delivering is more efficient than 2 phase which in turn is more efficient than 1 phase. Similarly, going up in the number of phases result in increased efficiency as well, i.e. 4 phase is more efficient than 3 phase and 5 phase is more efficient than 4 phase,…etc.
