Aplicaciones Tecnológicas, leader for more than 30 years in security solutions against electrical storms, has revolutionized the sector by incorporating the Lightning & Earthing Smart Solutions concept.

Electrical storms are dangerous and sudden hazards that generate risks to both people and property. These risks can be minimized with classic lightning protection systems.

However, intelligent solutions go further, collecting data, transmitting it via the communications network and processing it, so that new information is generated, for example:

  • The monitoring and information in real time of storm phenomena to avoid occupational risks
  • The control and verification of the state of a set of assets and installations, prior to failures or malfunctions
  • Operational control to organize maintenance tasks, or to avoid inefficient, dangerous or unexpected situations



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 22,607,575 strikes, while the country with the highest lightning density was Singapore, with 163.08 strikes per Km2.

What is a dry thunderstorm and what are its risks? storm detection atstorm

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.

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.
