DEVICE FOR GROUNDING ELECTRICAL INSTALLATIONS Russian patent published in 1999 - IPC

FIELD: electrical engineering; grounding by means of external devices. SUBSTANCE: device has conductor running from electrical installation, connecting buses 2, strips 3, and vertical grounding electrodes 4 rigidly interconnected. Vertical grounding electrodes are installed at corners and on each side of regular hexahedrons made from common center; vertical grounding electrodes are mounted at ends of hexahedron starting from second hexahedron from center in the quantity of n_h-1,, where n_h is quantity of regular hexahedrons. EFFECT: reduced space requirement for electrodes driven in ground. 1 dwg
