Answer Posted / madhusudhan
A neutral point is a junction of Three phases in Star
distribution circuit. this neutral should be earthed to
maintain high potential difference between neutral and
phase. when ever there is an unbalanced load distribution in
three phase circuit a emf will flow from one phase to
another phase through this neutral point. due to this
voltage in neutral the the Potential dofference between
phase to neutral gets reduced. so to maintain 0 voltage at
neutral point, neutral has to be earthed to the earth pit.
