Grounding Electrical Distribution Systems

The first concern and the most important reason for proper grounding techniques are to protect people from the effects of ground-faults and lightning. Creating an effective ground-fault current path to assure the operation of overcurrent protective devices on solidly grounded systems and to limit the voltage-rise on equipment frames during fault condition is of paramount importance.

The next concern is building and equipment protection. In this case, providing low impedance bonding and groun...
