Lightning protection in buildings is crucial to avoid personal, material and economic damage. An Early Streamer Emission air terminal is a high-tech device that responds to the approach of a lightning strike, anticipating its capture of other elements within its protection zone, in order to conduct the discharge current safely to the earthing. To fulfil their functions, they must be installed after calculating their protection radius in such a way as to protect the desired elements, an operation that can be carried out using two different methods but with identical results: those proposed by the UNE21186 standard and by the Technical Building Code (CTE). However, an erroneous interpretation of the latter can be dangerous.

A total of de 2.409.799.364 lightning strikes were recorded worldwide in 2021. This number includes cloud-to-cloud lightning and cloud-to-ground discharges. The country with the most lightning strikes was Brazil, with 225,607,575 strikes, while the country with the highest lightning density was Singapore, with 163.08 strikes per Km2.
Nowadays, there is an increasing demand for guarantees that any equipment or tool is tested in accordance with the regulations to ensure its correct operation. Lightning is a phenomenon capable of causing great personal and material damage, but it is not possible to anticipate exactly when and where lightning will strike. However, it is vital that the systems designed to protect against the effects of lightning operate correctly and in accordance with current regulations. Aplicaciones Tecnológicas has the AT Research Center, one of the best-equipped laboratories in the world for testing Lightning Protection Systems (LPS), where the most demanding tests are carried out to measure the reliability of all its components.
