A grounding electrode consists of any buried metallic body responsible for dispersing current to the soil. The specific application has significant influence on the electrodes' arrangement and dimension. The arrangement can vary from a simple rod, connected to the transformer of a distribution line, to horizontal electrodes buried about 0.5 m deep in the soil composing the counterpoise wires of transmission-line tower footings, or the typical grounding grids of power system substations. The flow of lightning -related currents to the ground and ensuring safety conditions, in terms of distribution of the electric potentials over the ground in the region where electrodes disperse lightning currents into the soil.
