Abstract—Grounding is critically important to achieve equipment and personnel protection in Small Hydropower (SHP) station. Moreover, the performance of any electrical or electronic system is greatly affected by the state of earthing. The paper includes the purpose of grounding, basic knowledge regarding the objective, review of various research works useful for designing a safe grounding system and recent trends which can be employed in designing a sound as well as an economic earthing system. The aim of the paper is to carry out the review of the techniques and developments in Earthing System and suggest the loop holes if any.
Index Terms—Earthing mat, step potential, touch potential, ufer grounding
