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.
By definition, “a dry thunderstorm is a storm that has no or very little precipitation associated with it, but does carry electrical activity”. The absence of precipitation can create a false sense of security that poses a serious risk to the safety of people and structures. In this scenario, a system with sensors capable of detecting all phases of the storm and issuing warnings before the first impact can make a difference.
Aplicaciones Tecnológicas has joined the standards committee CTN 221 – Wind energy generation systems of the Spanish Association for Standardisation (UNE) to participate in the maintenance of the standard UNE-EN IEC 61400-24:2011 – Wind turbines. Part 24: Protection against lightning strikes.
Aplicaciones Tecnológicas S.A. has developed the precise solutions for the efficient management of grounding and lightning protection systems in wind farms, maximising occupational safety and cost savings. We are at WindEurope Bilbao 2022 presenting the advanced equipment SMART EARTHING MONITORING SYSTEM, WIND TURBINE SMART LIGHTNING LOGGER and ATSTORM®.
The correlation between anthropogenic aerosol pollution and lightning activity has been known for some time, although the mechanism connecting the two has not been identified yet. The lockdowns enacted to contain the COVID-19 pandemic were an unprecedented opportunity to further explore this relationship.
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.
