It is estimated that 2,000 storms coexist simultaneously on the planet and about 100 lightning bolts discharge on the earth every second. In total, this represents some 4,000 daily storms and 9 million atmospheric discharges every day. Therefore, 1.2 billion lightning strikes occur per year on our planet.

Lightning protection standards establish certain periods for the verification and maintenance of the installed systems, which may vary depending on the normative. However, one point is the same in all of them: a complete verification is necessary every time the installation has been stroke by lightning. Mechanical or electrical lightning event counters record these strikes with one account every time a lightning current passes trough them.

Exothermic welding and mechanical unions can have a similar application at a glance; however, their results and benefits differ greatly.

Exothermic welding is a chemical process which enables the molecular bonding of metals in a long-lasting way. It is applied to metal joints and its use is very widespread in sector such as rail and the electrical sector, in the grounding connections.

Transient overvoltages

The overvoltages known as transients, are very short duration increases in voltage, measured between two conductors, or between conductor and ground. These can be due to atmospheric electric discharges (lightning strikes) or to switching or fault processes (contact to earth or short circuit).

In 2019, a total of 2,353,476,704 atmospheric electric discharges were registered in the world. This number includes lightning strikes between clouds and, above all, lightning strikes produced from cloud to ground.

A "Technical Note of Prevention" recently published in Spain assets that electronic start-up provides significant security enhancements

The frequency inverters are sophisticated equipment with microcontroller technology. For this reason, they are very sensitive to voltage transients and therefore suffer a lot of damage.

Aplicaciones Tecnológicas, S.A new general lightning protection catalogue is already available in our web page in 4 languages: Spanish, English, French and Portuguese.


Aplicaciones Tecnológicas has trained Work Health and Safety managers about the regulations in the field of Lightning Protection.

Lightning rods with the most advanced technology from Aplicaciones Tecnológicas, DAT CONTROLER® REMOTE, protect Malacky Castle in Slovakia, as well as part of the Zamocky Park, the classicist style English park that surrounds this 17th century fortress.

Aplicaciones Tecnológicas increases safety in theme parks by means of protection and prevention systems to minimize risks produced by lightning strikes. Dreamland Margate Theme Park located in Kent (England) is one of the last sites which has been protected by the company, where Aplicaciones Tecnológicas has provided the lightning protection system and the preventive system ATSTORM®, a local thunderstorm detector. 

Electric and electronic equipment may suffer important damages even due to secondary effects of lightning.

The National Pantheon of the Heroes and Oratory of the Virgin Nuestra Señora Santa María de la Asunción is an emblematic building located in the capital city of Paraguay which, at the moment, is under restoration.

Substations are the main centres for power distribution to the population. Their earthing must have a low resistance and being long-lasting and therefore the use of exothermic welding is recommended.

Find out the risk assessment for buildings or installations with our easy-to-use software, in line with the most relevant standards in lightning protection IEC 62305 and NFC 17102.

Nowadays, around 25 million lightning strikes impact the earth every year. In relation to the frequency of the lightning strikes, some research studies point out that the heat and a rise in temperature are related to cloud electrification. In fact, it is known that during the summer, thunderstorms are more frequent.

This reasoning could make us think that if the climate change produces a global rise in temperatures, an increase in lightning events could be produced.

DAT CONTROLER PLUS air terminals, together with our protectors from ATSHOCK and ATCOVER series, protect public and tourist facilities.

Aplicaciones Tecnológicas S.A. launches ATDB9, the surge protector for data lines wich connect highly sensitive equipment and besides they usually store valuable information.

Aplicaciones Tecnológicas, S.A. submitted several papers dealing with novel theoretical and practical aspects of lightning protection

Protects against transient overvoltages, permanent overvoltages and undervoltages, includes self-reclosing feature.

Photovoltaic power plants are always located in huge and isolated areas or on roofs due to their functions. They are high-cost equipment and when damaged can cause losses to energy supply, especially if they are connected to the distribution network. Its operation is controlled by sensitive electronic devices that can be highly damaged by transient surges. Therefore, from the point of view of lightning protection they are high-risks installations.

Renewable energies present new challenges in the field of lightning and surge protection for direct current lines. Therefore, Aplicaciones Tecnológicas S.A. has developed a new range of surge devices for the protection of direct current (DC) systems up to 1500Vdc, according to the IEC-61643-31 standard and the REBT-BT-23 Guide.

Thunderstorms are unavoidable natural phenomena that pose serious threats to goods, services, environment and even cause death to people. The mining industry is really vulnerable to these meteorological events due to the fact its operations take place in open areas and the activities involve the use of heavy equipment and the handling and storage of flammable materials, which increases the risk for employees (Occupational Safety and Health Administration, 2016).

The causes of these fires are usually human failure or faulty electrical installations, but landmark buildings have also been destroyed by fires caused by a lightning strike.

Its small size makes it easy to install inside the electrical conduits, very close to the luminaires


Only nuclear waste experts, provided with the appropriate protections, can remove radioactive lightning protection installations

Homes and business premises contain an increasing number of electric and electronic equipment, with more complex and essential functions. The damages due to overvoltages can be very serious for computers or TVs including peripherals, which are becoming more expensive and sophisticated. 

Lightning is one of the most fascinating and spectacular natural phenomena. The powerful electrostatic discharge that it represents lights up the sky during electrical storms.

Nevertheless, we must not forget that lightning strikes Earth with great force, and without appropriate protection and prevention it is potentially hazardous for people, animals, buildings and electrical and electronic equipment.
