Duval Messien – Our Know How – Protection

DIRECT PROTECTION: LIGHTNING RODS

The function of the lightning rods is to capture lightning to flow it to the earth along down conductors. Duval Messien manufacture and install lightning rods of 3 categories :

Simple rod (passive points) adapted to low dimensions areas.

Early Streamer Emission (ESE), derivative from the previous one, but whose effectiveness is multiplied by an electronic device which generate high voltage impulsions, which amplify the corona effect reducing then the meeting time between the ascending and descending tracers. It is used for more important areas. STORMSAT ® lightning conductor with integrated detection sensor and counter, SATELIT ® range from Duval Messien, use components which come from different technologies. They are both performant and reliable.

SCHEME EXAMPLE OF AN ESE PROTECTION  

Meshed cage or tight strand protection inspired by «Faraday cage », is composed if necessary of small points installed around the building on the protruding parts, at regular distances. These points are connected between each other with a meshing either composed of conductor installed on the roof, either with tight strands installed above the structure to protect. Lightning rods of this category share the wave shock flow with the meshing between the several down conductors.

INDIRECT PROTECTION : SURGE PROTECTIVE DEVICES

People safety is the priority for Duval Messien. Nevertheless, installations safety was necessary by the vulnerability of the equipments with new technologies.
With its philosophy of global protection, Duval Messien takes care of the protection against indirect lightning :  induced overvoltage, main causes of sensitive materials damages. They are responsible of computers and telephone networks breakdownw , direct destruction of phone cards or premature aging of components. After study of the installations, Duval Messien proposes efficient solutions installing specific materials at each sensitive tool. Duval Messien takes also in charge the conception and the design of the equipotential ground plan adaptes to all type of constructions.
