In a grounding system, the ground electrode provides the physical
connection to the earth and is the instrument used to dissipate current
into it. There are two main types of electrodes.
“Natural” electrodes are intrinsic to the facility
and include metal underground water pipe, the metal frame of the
building (if effectively grounded), and reinforcing bar in concrete
foundations.
“Made” electrodes are installed specifically to
improve the performance of the grounding system and include wire
meshes, metallic plates, buried copper conductor and rods or pipe
driven into the ground.
The ground rod is the most widely used grounding electrode. ERICO®
is the world's largest manufacturer of ground rods and offers a
complete line of rods and accessories to meet the needs of every user.
