The specific function of INGESCO® PDC lightning rod with ESE is producing an upward stream of ionized particles that will channel the eventual electrical discharge from its origin.
There is a difference in the electrical potential between the discharger (that has the same potential than the air around it) and both the air terminal tip and the deflection ensemble (they have the same potential than earth). This difference increases as atmospheric potential becomes higher because of the imminent lightning strike.
Knowing the value of this difference Δt allows us to make a relation between time and propagation speed of the electrical discharge, and, consequently, to calculate the lightning impact distance and the protection radium that offers each lightning rod model (see table below).
Knowing this value allows for the selection of the most appropriate lightning rod model taking into account the characteristics of the structure we want to protect and the level of protection needed according the norms UNE 21186:2011, NFC 17-102:2011 and NP4426:2013.
Characteristics
The capture terminal of INGESCO® PDC fits the following technical specifications:
- It has a double ESE (Early Streamer Emission) system.
- An early streamer device that produces the upward emission.
- An electro atmospheric condenser.
- An atmospheric accelerator.
- An insulation system certified by the General Testing & Research Laboratory of the Generalitat of Catalunya (LGAI).
- An external structure made from stainless steel AISI 316L.
- Early Streamer Emission system made from stainless steel AISI 316L and polyamide PA66.
- Its effective operation in any atmospheric condition and environment is thus guaranteed.
