Quality Charter and Sustainable Development The Sustainable Quality Assurance, our differentiation : France Paratonnerres is a human-sized French Company, specialized in the Research, the Development and the Implementation of devices of protection against the lightning. Strong of 40 years of experience feedback on more than 50 countries all over the world, France Paratonnerres, is certified: ISO 9001, Qualifoudre, Verteego Carbon, And differs in its technological choices, by the concept Sustainable Quality Assurance offered to customers. As it is difficult to finalize reliable technologies, France Paratonnerres leans on its Research laboratory, associates its teams, its suppliers, its scientific and industrial partners, in the eco-conception of quality products, patented, sustainable in time. This Sustainable Quality Assurance is translated by protection devices with reliability which guarantees their duration in time.

GENERAL INFORMATION ABOUT LIGHTNING The lightning phenomenon Origin, Lightning triggering, Localisation, Figures Lightning is a natural phenomenon of disruptive electrostatic discharge which is produced when static electricity accumulates between a cloud and the earth. The different electric potential between the two points can be up to 100 million volts and produces plasma on discharge, causing an explosive expansion in the air through release of heat. When it disperses, this plasma creates both a flash of light (lightning) and a sound (thunder). Lightning during fireworks Formation of or the...

The lightning phenomenon Lightning tends to hit high altitude areas and prominent objects. Thunder may resonate with a sharp cracking sound when the lightning is near and rumble when it is further away. As light travels faster than sound, lightning is visible before the thunder may be heard. geographic and climatic conditions to determine the level of exposure to the structure which is to be protected. The parameters notably: When the electrostatic field is over the dielectric limits of the air (variable depending on humidity and atmospheric pressure), a lightning discharge is produced and accompanied...

Without adequate protection, propagation of lightning current can lead to multiple effects which are divided into two main categories: direct and indirect effects: Direct effects Indirect effects • Mechanical effects take place when lightning strikes (such as distortion, break-off destruction, ...) Overvoltages are conducted when lightning strikes an electrical line or pylon directly. The current is propagated and reaches all the installations along the line, even several kilometres away from the point of impact. Overvoltages are induced by electromagnetic radiation of the lightning current on...

The detection network for storms at « Météorage » enables to determine the values of the density of lightning strikes over the whole of France. When density is not known for any one site, it can be deduced from Nk according to the following equation: Lorsque la densité n’est pas connue pour un site donné, elle peut être déduite de Nk selon la relation suivante : Depending on the geographical situation, of the type of electrical power supply or the presence or absence of an air terminal, the installation of a protection system against overvoltages may be compulsory as the following table shows:...

The lightning phenomenon Statutory NV65 (Snow and winds 65) in force since February 2009 were established to fix the values of climatic overvoltages and to provide evaluation methods for the efforts corresponding to a complete building or on its different parts. In respect of these rules, the France Paratonnerres extended poles have been designed to resist in extremely windy conditions without guying. However, it may sometimes be necessary to check the mechanical strength of the planned installation when a superior level needs to be guaranteed. France Paratonnerres will then recommend the right...
