An electrical substation is a critical resource in a power system. Safe operation of a substation calls for a properly designed and installed grounding system. A well-designed grounding system will ensure reliable performance of the substation over its entire service life. Web1.2 Problem statement Designing a proper substation grounding system is quite complicating. Many parameters affect its design. For a grounding design to be safe, it needs to provide a way to carry the electric currents into the ground under normal and faulted conditions. Also, it must assure that a person in the vicinity would not be endangered. … bamlegal
