Earth Rods and Lightning Arresters

The earth rods a small device used to protect all other devices from lightning or similar static currents. It is placing into the ground by connecting to the main electricity source. It has to be placed at least 2 feet distance from the source or building. It can be used as a remover of excess current or current leakage.

Earth Rods

Normally we are using lightning arresters to protect our whole devices and building from the sudden excess electricity. By placing the lightning arrester above the building or top of the building, It must be connected with the ground. T do the ground connection it has to be combined with an earthing rod.

In a lightning arrester system, a lightning rod is a single component of the system. To provide a protective function, the lightning rod needs to be connected with the earth. The common thing in all lightning rods is that they are all made of conductive materials that may be copper and aluminum.

Lightning Arrester

Earthing rods can be extended by design. It can be used with copper couplers to inter-connect many rods to acquire the required driving depth – the rod couplers provide permanent electrical conductivity and the longer copper earth rods access lower resistivity soils at lower depths.

Vertically driven earth rods are the most effective electrode for use in typically small area substations or when low soil resistivity ground conditions, For high soil resistivity ground conditions, where the rod can penetrate lies beneath a layer.

Lighting arresters are commonly using for all types of buildings. If it is not properly connected to the ground there is no use with it. If the earth rods are not placed, the excess voltage will return back to the source. If it is excess to the device, there is a chance for the failure of it and sometimes exposure can happen.
