LIGHTNING PROTECTION SYSTEM
Lightning is a natural phenomenon that cannot be prevented, therefore lightning protection systems need to be installed in buildings to reduce or eliminate the impact of lightning flash and safely discharge to the ground especially here in Africa since we are along the equator.
These system consists of the following five parts; air terminals (lightning rods), conductors, ground connections (electrodes), bending and lightning arrestors. There are two purposes for these systems in a building: Firstly, even though the occurrence of lightning cannot be prevented, the lightning protection system can provide a specific location for the lightning strike on the building by using air termination rods. Secondly, it will also provide the safe path on the electricity current from the lightning to be smoothly discharged to the earth.
The overall function of the system can be classified into several functions as indicated:
- Provide the proper point to intercept the lightning strike.
- Provide proper path for lightning current to earth.
- To dissipate current into the earth.
- Create an equipotential bond to prevent hazardous potential differences between the system structure and internal elements/circuits.
To reduce the risk of a system failure, it should be installed by a certified installer. Nationwide provides the best equipments to provide the perfect lightning protection system for you. To maintain a system’s certification, regular maintenance and annual inspection must be completed.
