Lightning Protection System

To intercept all lightning strikes entering a building

The purpose of a Lightning Protection System (LPS) is to intercept all lightning strikes to a building, redirect them to the ground, and distribute them evenly across the ground. In order to prevent dangerous flashovers and lightning-caused fires, all metallic installations in the building must be made at equal potential. An LPS is regarded as the most effective measure for protecting the structure and its contents against physical damage or degradation. The goal is to prevent thermal, mechanical, and electrical effects that can cause damage to the protected structure or to humans via touch or step voltages within the structure.

Main protection measures against injury to living beings due to touch and step voltages are intended to:

Reduce the dangerous current flowing through the body by insulating the exposed conductive parts or by forming an equipotentilisation
Reduce the occurrence of dangerous touch and step voltages by physical restrictions and/or warning notices LPS comprises of External LPS and Internal LPS.
