Answer Posted / sarmadahmed
The earth connection to neutral (or neutral grounding) has no disadvantage. In fact, it provides safety to the electric equipment. If neutral is solidly grounded then fault current for SLG fault will be greater than that of 3phase fault. So the protective devices should be of higher value. That could be the only disadvantage.
