A Newly On-Time Following Up Electrical Earthing System Technology

The electrical earthing/grounding for power systems is very important to restrict the residual current from any unwanted fault and reduce undesirable outage and prevent shock hazard. Many factors can affect the earthing system; corrosive soils with high moisture content and high salt content...etc. The proper design for earthing system depends on many parameters and must be carefully measured in the installed earthing site “i.e. moisture, temperature, salt contents...etc.”. In most cases, after determining the earth resistance system referenced to the standard values, there is no followed up by preventive maintenance during the life time of earthing system which leads to serious defaults in safety system. This paper introduces an actual model system which is a newly on-time automatic measuring and correcting earthing site system. The proposed technique uses an Aurduino program integrated with suitable electromechanical and electronic equipment as inputs and outputs corrected parameters. This is intended to solve problem associated with variations of earth resistivity from reference “accepted” values due to soil contents such as; moisture, temperature and salt values. It has the benefits of two instruments; soil resistivity and earth resistance instruments by simple and very cheap proposed system related to the commercials instruments in markets. The newly technique can provide continuous protection for operators against touching /step voltages, equipment hazards and damages by the corrected actions and the maintenance staff messages.
