A lightning protection system is only effective if it continues to perform as designed. Corrosion, loose connections, construction work and general wear can all reduce a system’s protective capability over time.
Why Regular Testing Is Required
SANS and IEC standards call for periodic inspection and testing of earthing and lightning protection systems. Without testing, faults can go unnoticed until a strike exposes them, which is the worst possible time to find a problem.
What a Test Includes
A typical test covers continuity of all bonding and conductor connections, physical inspection of air terminals and down conductors, and measurement of earth electrode resistance.
Recommended Testing Frequency
Standard commercial buildings are generally tested annually. Higher risk sites, such as those storing hazardous materials, may require more frequent testing as part of their risk management plan.
Keeping Records
Test results should be documented and kept on file. This record demonstrates compliance and gives a clear history of the system’s condition over time, which is useful for insurance and audit purposes.
