They are very deadly, but the Arkoddians have learned to handle them with grounding rods.

Ufer grounds, when present, are preferred over the use of grounding rods.

In Australia, locations with very dry soils need the grounding rods to be extra deep.

I'm a contractor so I put some American flags on electrical ground rods in front of my property.

The wellhead and the ground rod form the two electrodes of a dipole antenna.

As an expediency, the transmission line can be connected directly to the end of the antenna and a ground rod usually with satisfactory results.

A large grounding rod connected to both the antenna and the mast or pole is required.

Some used dedicated ground rods.

Heat flashed through her, lightning scorching a path down a grounding rod that was her nervous system.

If the building has significant metal framing elements, these should be bonded to the lightning rods and grounding rods as well.

A 470 ohm non-inductive resistor is installed from the far end of the wire to a ground rod, although this value is not critical.

Grounding, union of ground rods to metallic structures, meshes, substations, power installations and lightning arrestors.

This gradient is low at points far away from the earth return connections, but increases near the ground rods where the metallic circuit enters the earth.

Another issue is that the resistance may be high enough that insufficient current flows into the earth neutral, causing the grounding rod to float to higher voltages.

During dry weather, the ground connection often developed a high resistance, requiring water to be poured on the ground rod to enable the telegraph to work or phones to ring.

In order to safely dissipate this collected sky voltage, one current-carrying wire of the electrical grid is connected to a grounding rod at regular intervals throughout the power system.

The lightning charge passes to wire conductors alongside the house (either inside or outside the walls), which are connected to ground rods driven into the earth about two feet from the house.

A resistor connected to a ground rod terminates the end of the antenna pointed to the target area, a 470 ohm non-inductive resistor provides excellent results for most soils.

Lightning protection is provided by bonding the multipoint ground grid to one or more grounding rods under or at the perimeter of the building, and then up to the lightning rods.

The job of the Static man is to use a grounding rod to attach to the hook so that the static electricity conducted by the helicopter is grounded out and does not end up killing a Marine.

The ends of the transmission lines were grounded by 1 to 3 miles of buried copper cable and ground rods, later replaced by arrays of electrodes in deep 300 ft. boreholes, to reduce surface ground currents to address environmental concerns.

For particularly demanding applications, the main technical ground may consist of a heavy copper pipe, if necessary fitted by drilling through several concrete floors, such that all technical grounds may be connected by the shortest possible path to a grounding rod in the basement.

The substation feeding such lines has a grounding rod on each pole within the substation; then on each branch from the line, the span between the pole next to and the pole carrying the transformer would have a grounded conductor (giving each transformer two grounding points for safety reasons).

When ground soil has poor conductivity, is very shallow, or non-existent, a grounding system can be augmented by adding ground rods, counterpoise (ground ring) conductor, cable radials projecting away from the building, or a concrete building's reinforcing bars can be used for a ground conductor (Ufer Ground).

If your plumbing contains plastic supply pipe, or if the municipal supply is electrically insulated less than 10 feet from the house, look for a metal grounding rod or cable embedded in the earth outside the house near the panel (a wire from the panel should run to it) and fasten the clamp to it.
