neutral is reference from where phase voltage is
measured also it serve the purpose of return path
in three phase.it is possible in Y connection .in
delta it is virtual.while earth is always at O
potential.

it is used reduce the shock hazards in equipment.

earthing is done by connecting the equipment with earth using conductor.
there is no as such method.

there is 3 methods of neutral grounding(not earthing)
1.solidly ground
2.RNS
3.INS
