GROUNDING SYSTEM FOR TOWERS OF OVERHEAD POWER LINES
The invention relates to a grounding system for a tower of an overhead power line, wherein said tower is anchored to the ground by means of one or more anchorage structures (1) at least partially buried. The grounding system is buried and comprises: a first electrically conductive ring-type grounding element (21) which is buried at a first predefined depth, extends horizontally around the anchorage structure (s) (1) of the tower and is electrically connected to the tower; a second electrically conductive ring-type grounding element (22) which is buried at a second predefined depth greater than the first predefined depth, extends horizontally around the anchorage structure (s) (1) of the tower, is larger than the first ring-type grounding element (21) and is electrically connected to the first ring-type grounding element (21) by one or more grounding conductors (24, 26, 28); and one or more micropiles (23, 25, 27, 54) which are electrically connected to the second ring-type grounding element (22), extend vertically or obliquely downwards from said second ring-type grounding element (22) and are configured to act as deep earthing elements.
