In Power system networks and installations, it is of absolute necessity to consider the safety of personnel and the entire installation right from the planning and design stages. Thus, plans are made to provide for situations of over current in a short-circuit situation and means of isolation of faults between connected systems to avoid unending propagation. Two primary concerns in mind are: Safety of personnel, and property against overvoltage mishaps. Neutral-grounding is a System used to

It is of different types and implementation and the choice of system depends mostly on what the designing or installation Engineer seeks to achieve. In this work, the ungrounded as we as different methods of neutral grounded systems were studied. The work showed in simple terms the effectiveness of neutral grounding and its advantages over the ungrounded. The results obtained are thorough research from different works that had been carried out on this subject and also from results and experiences obtained from the field. For an efficient practical neutral grounding result, the space between the earth rods must be the same or slightly greater than the length of the individual rods.
