Abstract: The present invention relates to a system for maintaining and controlling earth resistance. The earth resistance is maintained by controlling moisture of earth using moisture sensor. The main component of the proposed earthing system is smart earthing kit which limits the leakage current. Soil moisture sensor senses the moisture of the soil and gives data to the micro-controller. If moisture decreases microcontroller operates solenoid valve through opto-isolator and water supplied to soil. If the fault current is excessive than the conventional earthing capacity then controller circuit sense this excessive current and divert this leakage current into Smart earthing kit.
Keywords: Earthing, smart earthing system, excess current, dry earthing surface.
