Telecommunication towers such as mobile phone, television or radio repeaters are high rise structures, often located in isolated places and equipped with sensitive elements susceptible to atmospheric electrical discharges. Their maintenance and repair usually requires technician call outs to remote locations, which creates an important cost and loss through downtime. ...

Exothermic welding, also known as aluminothermic welding, is a chemical process which creates a permanent molecular bonding of two or more conductors. As a result of this fusion, the connection is more reliable and durable than the mechanical union, and its conductivity is equal to or greater than the metals it connects. Where is it used? It is used in earthing syste...

Typically, these devices have a three-phase supply input with a neutral and a three-phase output without a neutral, which normally supplies power to pumps. Types of surge protection for frequency converters: ATSUB-4P-NR 40 TT(Ref.: AT-8030) For the protection of the general input of the MCB (Mechanical Circuit Breaker), a type 2 transient overvoltage protector is ...

Agricultural and livestock farms make efficient use of the resources provided by their natural environment. The animals that are raised in freedom and in adverse weather conditions are at risk of being directly or indirectly struck by lightning. Agricultural and livestock farm risks in the event of thunderstorms: · Direct lightning strike · Step voltage risk If t...

One of the most recent is the study of the expected increase in storms in Europe, based on the detection of lightning and the observation of damages: Rädler, A.T., Groenemeijer, P.H., Faust, E. et al. “Frequency of severe thunderstorms across Europe expected to increase in the 21st century due to rising instability”. npj Clim Atmos Sci 2, 30 (2019). In this article, t...

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. Theme parks are sites prone to lightning strikes Speed, adrenalin, excitement… A visit to an amusement ...

Summer period is traditionally the season where good weather and holidays are most enjoyed, but it is also the time of year where more cumulonimbus convective clouds are formed which produce lightnings. Every summer, news about fatal outcome accidents involving people due to an inadequate protection, resurface. Moreover, these discharges are one of the leading causes ...

Both exothermic welding and brazing are different methods of bonding one or more pieces of metallic conductors used in earthing systems. There are different types of welding and different forms to classify them. One of these forms is to distinguish if the pieces to be welded are actually melted or not when adding the compound material. Brazing is a welding process in ...

Any interception system (lightning rod) should meet the national and international standards or laws that are applied to it (mainly standards UNE 21.186, NFC 17.102, Technical Building Code SU8, Series IEC/EN 62.305 and IEC/EN 62.561). How is a lightning rod installed? The lightning rod, in order to fulfill its function, must always be installed above the highest p...

There are two relevant data facts to keep in mind when evaluating the danger of lightning in golf courses. Firstly, the annual average of death casualties in golf courses is 13 people worldwide, being the majority due to electrical discharges caused by storms. Secondly, 5% of the total deaths caused by lightning strikes in the US occur in golf courses. According to st...

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. Aplicaciones Tecnológicas S.A. has all the elements available to achieve the best protection for solar plants: effective lightning rods for capturing lightning, special ...

They protect the electronic circuit inputs of network cards against damage caused by surges. The power supply via Ethernet, called PoE (Power Over Ethernet), uses data lines to power the equipment as well. It is used in systems such as IP phones, access points, IP cameras, routers, etc. The latest generation PoE++ lines can transmit currents of up to 1 amp. Poe sys...

It regulates the quality, safety and electromagnetic compatibility requirements for protectors against permanent or temporary overvoltages, also known by their acronym POP (Power Overvoltage Protectors). This publication extends the existent European standard EN 50550:2011, modifying some points such as the classification of the protectors, but maintaining the operati...

Several standards establish the requirements for lightning and surge protection systems. Below, we summarize the most relevant: · Lightning protection systems There are several national standards that give the requirements for lightning protection using Early Streamer Emission (ESE) air terminals: UNE 21186 (Spain); NF C 17-102 (France); NP 4426 (Portugal); TS 137...

The National Institute of Occupational Health and Safety, an agency belonging to the Ministry of Employment in Spain, has recently published a Technical Note of Prevention for occupational hazards caused by lightning strikes, in which Aplicaciones Tecnológicas has collaborated as experts in lightning and surge protection technologies. The formation of lightning is impos...

Due to its great architectural and patrimonial value, guaranteeing the safety of this construction is essential and that is why the building has been equipped with an ESE lightning arrestor from Aplicaciones Tecnológicas. This lightning rod is certified according to the current regulations and is completely autonomous allowing for in situ verification status. The monume...

This device acts against both transient and permanent overvoltages and is pre-wired, with an integrated miniature circuit breaker. With a 4DIN compact size, it is especially suitable for installation in a reduced space of a distribution panel. Due to its configuration as a two-in-one device, with the IGA TEST SUB M it is not necessary to replace the whole device at the ...
