Because 3-phase is the way electric power is generated, transmitted and distributed. The 3-phase format is broken down into single-phase supplies only at the consumer level, so that you might be on red phase while your neighbour on one side is on yellow and the neighbour on the other side is on blue.
3-phase is used all over the world for all significant amounts of electric power because it can be distributed using less cable and therefore less power-loss. Three single-phase supplies need 6 wires, while a 3-phase supply takes advantage of the phasing to use only 3 wires for the same power. Each pair of live wires acts as the return wire for the other wire in a symmetrical and balanced system.
What else can I help you with?
Can a 415volt 3phase motor run on 525 volt 3 phase?
It is not advisable to run lower voltage motor on a higher voltage.
Why wattmeter shows negative reading during no load condition of 3phase ac induction motor?
no load means the motor is acting like a coil
How much will neutral current be in a 3phase 4-wire y system with a balanced load?
Balanced load means no unbalanced currents, so the neutral current should be near zero.
Why do we use 1.73 as multiplication factor to calculate Phase to Neutral voltage?
because 3Phase power - V X I X Cos Phi X Square root of 3 and square root of 3 - 1.73
Why do you use single phase in house wiring?
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)
