Lightning strikes, as mentioned in our previous articles, trigger fire risks due to their extremely high temperature of approximately 28,000 degrees Celsius. Since electrical energy is converted into thermal energy, lightning strikes can cause fires in all types of structures. For this reason, every facility must be equipped with an external lightning protection system.
In addition, a lightning strike can reach peak currents of up to 200 kA and may destroy all systems within 100 nanoseconds. To protect against these electrical effects, it is essential to use an
low-voltage surge protection device (AG SPD) system.
The photographs show real-life examples of damage caused by lightning strikes as a result of equipotential bonding differences, insufficient external lightning protection systems, and the absence of internal lightning protection measures.
