Various Aspects and Analysis of Earthing/Grounding System for Protective and Functional Applications

Abstract

Earthing or grounding means connection of neutral point or body / enclosure of a system with the ground mass to avoid any accident & smooth functioning of system whether it may be power system, fuel pipelines,  telecomm, lightning protection or data processing centres. It will transfer the undesired charge directly to the ground because impedance of such path will be very low. Earthing/Grounding is low impedance return path to fault currents. Earthing should provide at generating station/ESS (Electrical Sub Stations) & consumer’s premises as required. Presented paper is focussing on earthing essential, systems, design calculations, standard practices & applications.
