what is 3 phase power? How does it work? How does it differ from 1 phase power that most residentials have? Why isn’t 2 phase power as popular?
In: 1
3 phase power is preferred because it applies a constant torque to a motor and has no current flowing through the neutral when the load is balanced. With single or two phase power the amount of power being transfered to the load varies with time which puts more strain on rotating machines and is less efficient. You can achieve the same thing with even more phases, but there’s no benefit, only added complexity.
