SPARC software

LogoSPARCFor a Lightning Protection System it is mandatory to calculate the separation distance. A simplified calculation is possible according to standards but for various cases (mesh system, many ESE on a roof etc.) a simplified calculation is no more possible and it is necessary to calculate accurately this separation distance, and this is only possible thnaks to a dedicated software*.

To meet this need, a software named SPARC (SPArkover Risk Calculator).

Contact us at (info@seftim.fr) for any details or for a live demo. You can also download related documents : user manual and technical leaflet.

Launch of SEFTIM East Africa

RwandaFlagTo continue its development and to be present in the most severe areas of the globe regarding lightning activity, SEFTIM is pleased to announce the launch of SEFTIM East Africa with an office based in Kigali in Rwanda to radiate in the region. It is with great pleasure that we welcome this new entity into the SEFTIM family.

Lightning protection does not only concern industry and agriculture, but also the protection of people. Rwanda has paid a heavy price recently with 16 people killed by lightning and 140 wounded in a church in Rwanda on March 10

Chairmanship of the European Lightning Protection Standard Committee

CenelecThe permanent Secretariat of the European Standardization Committee (CENELEC) « Lightning protection » TC81X belongs to Italy. He attributed to our lightning expert Alain Rousseau the function of chairman of the 81X committee. It is an honor and a privilege to have been chosen by this Committee and this Secretariat whose level of requirement is known in particular to develop a lightning protection more and more rigorous. Alain Rousseau, succeeds to Christian Bouquegneau of the University of Mons, with whom SEFTIM has already done conferences on lightning and who has just retired. This post is also the right time to pay tribute to the work of Christian Bouquegneau not only in the field of standardization (IEC and CENELEC) but also for his scientific work and his work in the field of lightning in art or the history of Lightning.

Training in New Caledonia

MineNCAs part of one of our actions in New Caledonia, SEFTIM has trained a part of the technical staff of a mining company operating nickel deposits. This training week was by chance, the week with the biggest amount of storm of the year on the main Island (grande terre). A total of 300,000 lightning arcs have been recorded by the weather office since the beginning of the year with a two-week spike covering the training period.

ONSE

ONSEONSE: In France, for more than 20 years, the association Promotelec and Consuel, supported by FASE (action fund for electrical safety), gathered actors committed to pool their data to analyse the evolution of electrical safety and improve it.

Each year, a plenary session, usually in December, provides an opportunity to present the work and results achieved in the relevant year by the ONSE Statistical Working Group.

The APF approached the ONSE with the aim of allowing the introduction of lightning data in the ONSE statistics. As such SEFTIM participated in the plenary session of 2017. http://www.onse.fr/ (in French)

30 years of Meteorage

météorageMétérorage, the French and international detection network, was celebrating its 30th anniversary this Thursday, November 23 in the prestigious premises of the Economic, Social and Environmental Council at the Palais d’Iéna in the 16th arrondissement of Paris.

  • After the emotionally charged introduction of Mr. Dominique Lapeyre de Chavardès, President of Météorage, Louis Bodin head of the weather service at RTL since 2002 and presenter of the weather reports on TF1 gave a very humanistic presentation on the weather and climate change. Météorage’s customers and partners then followed one another to explain their needs and then the shareholders Météo France and Vaisala to end up with a round table to answer the questions of the amphitheatre.

météorage30yearsSEFTIM from its side, gave a short presentation focusing on 3 themes:

  • Lightning Risk Analysis for which Météorage can provide lightning density in France and worldwide as well as data on the stormiest months, the statistical distribution of lightning currents and also the extreme currents.
  • Expertise following an incident where Météorage can provide lightning impact data with the location, the amplitude of the lightning current and its timestamp.
  • Standards: Météorage participates in standard activities (and in particular MT17 animated by SEFTIM) and carries out scientific publications to take into account the most relevant parameters of lightning strikes.

IEC TC81 MT 17 meeting in Austria

IECThe second meeting of Working Group 17 in charge of storm detectors was held in Vienna on the premises of ALDIS, the Austrian Storm Detection Network (https://www.aldis.at/en/). SEFTIM is the leader of this working group.

The aim of the working group is to publish edition 2 of IEC62793 (Thunderstorm Warning System) for storm detectors (networked: LLS Lightning Location Systems), local or grouped in a set of local sensors forming a mini-network. The classification of the various means of detection should be clearer and robustness tests which are for the moment only optional (and indeed very little performed) should become mandatory to ensure a longer life for the user and also reliable and validated information.

 

 

aldisThe various parameters such as the lead time -time to clear), the number of lightning strikes not detected or the rate of false alarms should be specified with particular influence of each of these parameters on others, because obviously they are all related and improving one often means degrading others.

 

As a reminder, the European standard EN 50536 on the same subject has recently been cancelled in favour of the IEC standard.

17th APF forum (French Lightning Protection Association)

APFThe now-traditional forum of the APF was an opportunity to bring together the various stakeholders in the field of lightning protection for a day of presentations and debates.  SEFTIM as moderator of the group in charge of the project, presented the progress of the « The lightning protection guide for individual housing » a normative document which should allow a simplified implementation of the protection of private dwellings.

forumAPF2017This document gives the principles of realization of a lightning protection installation for the individual housing of less than 500 m² and exclusively for the not dividing dwellings, for the protection against direct lightning strikes as for the protection against overvoltages due to atmospheric origin.

The lightning protection installation must be carried out by a skilled company in the field of lightning protection and having qualified personnel for this type of implementation.

It does not apply to collective housing buildings or services, industrial and agricultural structures.

The document prepared by APF must now be discussed in lightning protection committee (81) of AFNOR before publication.
