A system of buried or submerged electrodes connected to the positive terminal of an independent source of direct current, in order to lead to earth the current used for the cathodic protection of a buried or immersed metallic structure.

grounding cell
Two electrodes of zinc or other sacrificial material that are separated by insulating spacers and packaged in low-resistivity backfill material.

NOTE: These provide, for surges and alternating currents, a low-resistance path between sections of a structure and from structure to earth but drain only a small direct current from the cathodic protection system.
