What is Lightning?
Lightning, which is a fractal event with its light (flash) and sound (thunder), is the best-known natural phenomenon known to everyone. It is a result of the meeting of intra-cloud ionizations with the earth surface as a result of water droplets turning into ice crystals, created by Cumulus clouds.
How is the distribution of lightning within Turkey?
*Lightning strikes every point of Turkey, and 7,000,000 lightning discharges have been recorded in the last 2 years. Although lightning impulses, seen reaching up to 300kA levels, are more concentrated in coastal regions, they pose a risk for every point of Turkey; In just 2 days of hail experienced in Istanbul in the summer of 2017, 6000 lightning impulses were recorded.

How are Lightning Protection Ways Classified?
Integration of 4 systems is essential to be protected from Lightning. These are classified as External Lightning Protection, Internal Lightning Protection (LV SURGE ARRESTER), Grounding, and Equipotential system.
What is the International Standard for Lightning Protection Systems?
IEC 62305 1-2-3-4 is the lightning protection standard valid in our country as well.
What is Turkey’s Largest Lightning Protection Organization?
Lightning Protection Center (Yıldırımdan Korunma Merkezi) is the most comprehensive organization capable of providing all aspects of project design, sales, application, and reporting on all subjects and exceeding the threshold of 100,000 application points in this regard.
What is Lightning Protection Risk Analysis?
It is the system where all data of facilities are entered within the scope of IEC 62305 standard, and as a result, the risk potential is found, forming the basis of lightning protection designs.
How are Cameras Protected from Lightning?
For the lightning protection of cameras, energy, data, and coaxial lines must all be protected. For this, cat line protections and monophase products along with 12, 24, 48v weak current protection products should be used.
What is Free Lightning Protection Survey?
It is a system offered by Yılkomer on a Turkey-wide basis, where the deficiencies of the facilities are determined and reported.

Is it mandatory to have a Lightning Protection System installed?
In our country, it is mandatory to have an external lightning protection system installed for structures to obtain a license, but LV Surge Arrester electrical protection is definitely important in structures with external lightning protection. Therefore, integrated protection is of great importance.
What is the most common lightning protection method in the World?
The most common lightning protection method in the World is the Rolling Sphere Method foreseen by the IEC 62305 Standard.
