Ese Outdoor Lightning Protection Building Lightning Arrester
Lightning Rod Early discharge lightning rod has two actions. Action one: the use of thundercloud electric field, trigger device in the tip of the needle to generate high-voltage pulse, the formation of corona discharge. Action two: the pulling action through the venturi tube, so that the electric ion more powerfully to the tip of the needle. The upward pilot generated by the pulse will shorten the rendezvous time with the downward pilot.
This excitation device integrated in the air terminal is designed
to increase the excitation distance and thus generate the ascending tracer earlier(regarding to an ascending tracer naturally emitted by a simple rod. All of our early streamer emission systems are tested in compliance with NF C 17-102 standard,edition September 2011.
Specification Installation Guidelines 3 main components are part of a lightning protection system. .The
capturing device with its supporting mast and fixings. .The down
conductor composed of one or several tin-ned copper tape with
section in compliance with stan-dards in force,designed to flow the
lightning current of the lightning conductor to the earthing
system.This conductor will usually run outside the structure.Each
fixing should allow an eventual conductor dilatation.Bend radius
have to be inferior to 0.2 meters.Metalli-cal masses situated in
the zone of separation calculated beforehand will be interconnected
equipotentially to the lightning conductor.Each down conductor will
be equipped at the bottom with a control junction and a 2
meter-high mechanical protective tube. .The earthing system with an
adapted form in com-pliance with standards in force has for aim to
diffuse the lightning current to the ground.An inspection pit will
be installed to do the equipotential connection with the nearest
electrical earth netword of the building. Installation quality of a
lightning system is an impor-tant element ofr the efficiency of a
lightning protection system. For each installation and in most of
cases it will be bet-ter to start with the installation of the
earthing sys-tems,then as direct as possible channels of each down
conductor,then finish with the lightning conductor and roof circuit
installation. |
