In any system there are phase and neutral, where phase is
live while neutral is refrence wire. And this refrence wire
can be used to make the path availiable for returning
current.While its not necessary that this neutral may be at
zero potential(in case of faults).
But the ground is refrence with zero potential, in our
systems to increase capacity and fault current protection
Neutral point is grounded, this aslo prevents shock,
