In the power industry, safety is just as important a function as performance. Safety considerations, parameters, and methods of implementation are an integral part of any electrical system. A most important element is the grounding system. This system performs several functions, not the least of which is safety. Substations are active in fault clearance, and personnel working in and around them, as well as pedestrians passing in the vicinity, need to be protected.
