Neutral is grounded to protect against earth faults and to eliminate transient voltages. If not earthed we would never know that a conductor has fallen down and during this if another conductor falls down ,the fault current will be 73.2 % more.With one conductor fallen on ground the voltage between healthy conductor and the ground will be 1.732 times the normal
