LPS Lightning Conductors
Lightning protection systems (LPS) transfers the dangerous lightning currents safely to the ground. These systems usually includes the following: air termination, down LPS Lightning Conductors conductor and an earth termination system which is also better known as a grounding or lightning protection grounding system that is intended to provide a low resistance path to dissipate the high currents into the soil.
LPS lightning conductors are designed to provide a very low resistance path between the top most part of the LPS lightning conductor rod via a substantial strip of metal to the earth to ensure that the dangerous current as a result of a lightning strike does not flow throughout the building to which it is attached to.
The main purpose of a building’s LPS lightning conductor is to provide the mentioned low resistance path for lightning energy, rather than having the currents of the lightning bolt pass through the structure of the building and cause damage. Without the lightning rod, lightning is likely quite to strike the chimney etc. and can even start fires as it travels through the structure to ground.
Most of the newly build buildings especially the taller type buildings these days have proper LPS lightning conductors installed. LPS Lightining conductors carry the huge amount of electrical current caused by the lightning strike away from the building and safely guides it to the ground. In the case where an unprotected building is struck bu lightning, any moisture within the structure of the building can instantly turn into steam, with dramatic and catastrophic results.
There is no good reason why LPS lightning conductors (and the associated assembly consisting of a connection to earth and a ground rod) are not routinely added to houses. However, most high buildings and other structures do have some kind of lightning protection system incorporated into them.
Because lightning is most likely to strike the tallest object in the nearby vicinity, lightning rods are usually installed at the top most part of a structure and along its ridges as standard; they are connected to the ground by low-impedance cables. In the case of a building, the soil is used as the ground; on a ship, the water is used.
