Anneaux de mise à la terre

Un anneau de mise à la terre enfoui à l’extérieur est une technique qui aide à réaliser une faible impédance entre le système de mise à la terre d’un bâtiment et la terre elle-même, et un moyen commode de raccorder différents conducteurs et autres éléments de mise à la terre venant du bâtiment.

Ground Rod

A term which describes any metallic body in direct contact with soil, usually a copper clad steel rod that is eight (8) feet long and 5/8 inch in diameter. Eight (8) foot rods are placed at minimum 16-foot (length X 2) intervals on the Buried Earth Ground System (BEGS). Ground rods are usually copper-clad steel and a minimum of 8 feet long and 5/8-inch diameter. Longer and larger diameter rods are available. Stainless steel rods are required if objects of corrosion-prone metal are buried near the copper of the ground system.

Ground loops exist when there is more than one electrical path from a point in a circuit to a reference ground connection. Such parallel paths to ground are normally not a problem if associated with the non-sensitive circuitry located outside the Isolated Ground Plane (IGP). Ground loops are undesirable for equipment located inside the Isolated Ground Plane (IGP).
