We want to keep you informed about all the news related to Lightning Protection Systems (lightning rods, overvoltage protection and thunderstorm detectors) standard’s updates, specific training and workshops held at Aplicaciones Tecnológicas, as well as any application and download we develop in our company.
The protection against overvoltages in an electrical installation is vital to guarantee peoples safety and avoid short and long term damages to equipment. A large majority of the installations are protected against overloads and derivations, but the installed devices do not protect against transient overvoltages (due to lightning) and permanent overvoltages (for example due to neutral failures).
The fourth edition of ILPS, the International Lightning Protection Symposium, will be held this week, from the 23rd to 26th October 2018, in the Chinese city of Shenzhen. The symposium is organized by ILPA, the International Lightning Protection Association.
CINASE, National Circuit of the Electrical Sector, is the travelling technical event in Brazil that aims to bring together different experts from the electrical industry to discuss and present the progress made in the technological market.
The CINASE congress is held annually in Brazil and in this 2018 edition it is going to take place in the cities of Fortaleza, Canoas, São Paulo and will end in Rio de Janeiro in November.
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.
The general earthing system connects the different parts of an electrical installation with the surface conductor of the Earth to guarantee security and functionality.
In an electrical installation, the soil itself provides equipotentialization for all of the metallic parts so that there are no differences in potential between each other. This is carried out in order to guarantee the safety of people and equipment from any possible defects in the actual facilities.
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.
More and more buildings and houses have electronic devices that allow for a more efficient and comfortable home: thermoregulation, sophisticated security systems, all kind of automations, remote controllers, energy management systems, several interconnected devices…There is no doubt in there being a trend for domotised homes which will increase, given how these technologies mean an important improvement in the quality of life.
Lightning rods must undergo periodic inspections and maintenance, as indicated by national and international regulations (UNE21186, NF-C 17 102, IEC EN 62305). These periodic inspections of the lightning rod allow the detection of deviations from the reference standards or anomalies in the installation caused by environmental conditions such as corrosion, incorrect handling such as sectioning or robberies, or other circumstances such as expansions of the building where the lightning rod is located.
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.
An Early Streamer Emmision air terminal, also known as ESE or as an ionizing lightning rod, is an external lightning protection system with innovative technology. This ESE air terminal is also known as active lightning rod.
