SCHIRTEC-DA E.S.E. LIGHTNING CONDUCTOR

The main function of the lightning protection system installed on the existing building is to capture a lightning stroke and then conduct discharge current safety to the ground.

 
In some conditions, however the active lightning system is the only possible method to protect from direct lightning strokes. Due to the arguments mentioned above, we recommend to use the active lightning protection whenever the conventional solution is inconvenient or when the former is more preferable to the latter as in the case of the efficient protection of architect.

The lightning discharge is initiated by so-called down conductor which creates an ionised air path (downwards or upwards) between the cloud and the ground for the necessary flow of any lightning currents.

Operating Principle:

Principally, Schirtec-DA operates with the same technology like Schirtec-A, but Schirtec-DA has 2 operational parts. The first part is identical with the Schirtec-A. (technical information is written on its data sheet).The second part is an additional ion generator located in the down part of the body. This second ion generator is coated with a special material in order to protect the circuit from some environmental effects like corrosion, moisture etc.
The second ion generator has a different working method, so-called triggering arc. The triggering arc only occurs when the ambient electric field is high enough to ensure a stable upward leader can be developed to successfully intercept the downward leader. With the help of the second ion generator, Schirtec-DA provides usually a higher ΔT value than Schirtec-A.

Installation:

Schirtec -DA should be installed 2 meters higher up than the highest point of the protected structure. The protection level is depended on the height at which air terminal is installed and on its power and min.3 meters from medium and high voltage installations. It should be connected with down conductors lying on opposite structure walls.

DOWN CONDUCTORS
Material
Minimum Dimensions
Bare or tin-plated Electrolytic Copper Strip 30 x 2 mm
Round Section : 8 mm dia
Braided cable 30 x 3,5 mm
18 / 10-304 Stainless Steel Strip 30 x 2 mm
Round Section : 8 mm dia
A 5/L Aluminium Strip 30 x 3 mm

It is required an earth resistance less than 10 ohm.

A Lightning Strike Counter can be installed at the down conductor to count the flows of the lightning current.
