Question

Why we use 3-phase supply?....
​

Answer 1

Step-by-step explanation:

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.

Answer 2

Answer:-

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.

Its advantages:-

• Power to weight ratio of three phase induction motor is high as compare to single phase induction motor.
• Means for the same amount of Mechanical Power, the size of three phase induction motor is small as compared to single phase induction motor. Hence, the overall cost of induction motor is reduced.
