Besides, the intensity of a ground fault will be greater and will be accompanied by a flashover. This may be dangerous to personnel who are in the vicinity.
The damage to the equipment is also extensive as a higher current flows in solidly grounded system. The conductors carrying the current are subjected to extensive electrical and mechanical stresses.
The ground current which flows through the soil can pose a danger to people if the step potential exceeds the safe limits.
