In princible two things may happen during fault condition
or unballance loading:
1- No earth fault protection will be operated.
2- Any Phase/ Neutral voltage could reach the value of
Phase/ Phase voltage in magnitude.

Answer / raghavendran
If the system neutral is not grounded then during unbalanced
condition or during any faulty condition the excess current
will flow through the phases.During the condition of neutral
shifting the the current will flow into the system
itself.This will lead to damage to the equipment and the to
the personal working with the system.

During Testing of Maintenance Free Earthing, How deep should be the Spikes of Earth Test Meter should be inserted in the soil(one spike is 15 Meter & Other spike is 30 Mtrs away from the Main Earth Electrode. Because, recently, we observed that when spike is inserted 3-4 Inch in the earth- results are better, If spike is inserted 1 feet deep than results are increasing.
