Earthing, also known as grounding, is a fundamental and essential part of an electrical system. Despite not being a visible element, the earthing system is of vital importance for the safety of people and equipment, as it protects against dangerous potential differences.
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.
At Aplicaciones Tecnológicas we are experts in the execution of lightning protection studies and projects for structures and buildings. Let’s consider what would happen if these installations did not count on lightning rods?
In Aplicaciones Tecnológicas we have two new videos of our Apliweld® Secure+ exothermic welding, both of them explain the usage of the specific and multiple graphite moulds. Before starting the videos, its convenient to know the concepts related with this type of welding.
Lightning bolts are powerful atmospheric electrical discharges that pose a great danger depending on where they strike. Without proper protection and prevention, these discharges are a risk to people, animals, buildings, and electrical / electronic equipment.
In order to prevent the effects of this natural phenomenon, the UNE-EN IEC 62793 standard establishes an application guide to determine the need or not for a thunderstorm detection system, as well as the types of detectors that exist for it.
Aplicaciones Tecnológicas, leader in lightning protection systems, is organizing free online courses aimed at professionals in the sector.

The introduction of the tablet format in the Apliweld Secure+ system developed by Aplicaciones Tecnológicas implies innovation which has brought significant advantages for the implementation of exothermic welding in any earthing system.
A lightning strike is a natural event which significantly affects all outdoor activities and can pose a risk if the right preventive measures are not considered.
The data obtained by different institutions corroborates the high frequency of lightning strikes in sports events. According to the information gathered between 2006 and 2013 by The United States meteorological service (NOOA), 14% of deaths caused by lightning strikes happened during outdoor sports and leisure activities.
A surge is an increase in the voltage of the electrical network and It can cause damage to the installation and electronic equipment in your home. In the United States, electric shock claims to insurance companies were estimated to be $909 million. This amount claimed comes from 78,000 users only.
From the 26th to the 30th of October, several meetings were hold in Athens (Greece) of the International Electrotechnical Commission (IEC) groups that are in charge of re-viewing the 4 parts of the lightning protection standard IEC 62305 (General principles, Risk management, Physical damage to structures and life hazard, Electrical and electronic systems within structures).

Do not miss the chance to comfortably learn about the latest innovations in the sector with great impact on the prevention of occupational risks wherever you are.
A surge is an increase in the voltage in the electrical network that can cause damages to the installation and electronic equipment in your home. Your home, given the continuous digital transformation, contains even more electrical and electronic equipment, with more complex and important functions.
Lightning is a phenomenon that, despite being very common, is little known outside the specialized forums and creates uncertainty. It is important for people’s safety and to safeguard the equipment, that some key points are taken into account on what not to do in case of a storm:
This week the Technical Congress of the National Committee of CIGRE 2018 is talking week in Madrid. For two days, 27th and 28th of November 2018, companies and public and private organizations present their experiences with the objective of improving the high voltage power distribution.
APLIWELD® Selector is a tool, aimed at all professionals who need to perform exothermic welding, designed to facilitate the specification and preparation of the material in any project with aluminothermic welding. Thanks to the APLIWELD® Selector software, the user obtains product references and quantities of each material for all the connections required in a project, quickly and efficiently.
Aplicaciones Tecnológicas offers a wide range of products to protect installations and equipment against permanent overvoltages. This type of surge, unlike transient overvoltages, can last for an indeterminate period of time, causing significant damage to the equipment connected to the network, such as its deterioration or even destruction.
Several key factors should be considered when exothermic (also called aluminothermic) welding is employed, in order to make the best use of the resources invested in the purchase of material and to improve the work in site.
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.
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.
On August 13, 2019, the northernmost lightning known to date was detected, 52 kilometres away from the geographic north pole (89.53°N).

Lightning causes significant damages and losses all around the world, especially in those areas with higher frequency of thunderstorms and during the summer months. It is estimated that there are about 2,000 active storms every day and that approximately 40 lightning strikes per second on Earth, which means about 1200 million strikes per year. Some researches suggests that there could be an increase in thunderstorms due to climate change and pollution.
End of the 18th Century. Discovery of the electrical nature of lightning and the possibility of avoiding its damages by giving the lightning current a path to ground.

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.
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.
Permanent overvoltages are voltage surges above 10% of the nominal value of the distribution network which are maintained for several cycles or permanently. They are normally caused by a defective connection of the neutral or by a failure in the transformation centre.
Renewable energies present new challenges in the field of lightning and surge protection for direct current lines.
