Protection

ADAPTED SOLUTIONS FOR PROTECTION AGAINST DIRECT AND INDIRECT LIGHTNING IMPACTS

DIRECT PROTECTION : LIGHTNING CONDUCTORS

The role of the lightning conductors is to capture lightning to flow it into the ground by down conductors.Duval Messien manufactures and installs lightning conductors of three categories.

Simple rod, with sharp, steel points, derived from earlier designs.They provide protection for small structures.

Early Streamer Emission (ESE),a development of simple rod, but in which the efficiency is enhanced by using a device generated High voltage pulses to create a corona  effect. This reduces meeting time between the upward and the downward leaders and makes designs suitable for much larger structures.Duval  Messien  SATELIT  range  uses  components  from  different technologies. They have a high performance and reliability.

EXAMPLE OF A PROTECTION BY ESE 

Meshed

Meshed cage or tight strands, based on the « faraday cage », is composed if necessary of several strike points installed around the building and on its prominent features, at regular intervals. These strike points are connected to one another by meshes done with either, conductor installed on the roof, either with wires suspended above the building.

EXAMPLE FOR A MESHED CAGE PROTECTION

INDIRECT PROTECTION : THE SURGE PROTECTIVE DEVICES

Personal safety has always been a priority for Duval Messien.

Nevertheless,  installations  safety  became  necessary  by  the equipment vulnerability due to new technologies.Duval Messien’s objective is to provide global protection, which includes protection against indirect effects of Lightning: induced overvoltage, main causes of damages on sensitive equipments. It  can  lead  to  the  breakdown  of  computers  and  telecom networks, destroy phone cards and causes premature ageing of components.After installations study, Duval Messien proposes efficient solutions installing specifical material at each sensitive equipment. Duval  Messien  takes  in  charge  the  conception  and  realization of  implement  plans  for  the  equipotential  bonding  of  metal 
constituents in any type of constructions.
