ESE Lightning Conductor (LEADER)
Lightning is the most beautiful and the most deadly natural phenomena known. Its temperature is very hot like the surface of the sun and shockwaves beams out in all directions. it carries current in hundreds of Kilo-Amperes and is highly disastrous.
"Don't be a Target"
Install Leader® & prevent your installations from lightning strike hazards.
Atmospheric Discharge
Before an atmospheric discharge, a thundercloud - cumulonimbus - emits a series of ions known as down tracers or leaders. The negative polarity leaders fail towards the ground is successive fifty meter drops at speeds of 0.15 to 1m per us, wherease the positive leaders fall more steadily.
As they approach the ground, the tips of the highly ionized down leaders generate a powerful electric field that can reach several hundred kilovolts per several hundred kilovolts per meter. This powerful disturbance triggers the creation of opposite polarity up leaders, primarily at high and prominant spot along the ground.
As the down and up leaders join an joinzed channel to the ground filis with cloud. A return arc, known as the atmospheric discharge, returns through this joinzed channel. It consists of several arcs between the ground and the cloud.
The function of the Leader® Early Streamer Emission (E.S.E.) lightning conductor is to be preferred and obligatory lightning strike point for the entire area it protects. The most reliable and consistent way to create such a strike point is to exploit the important electromagnetic disturbances produced by the approachin down leaders just before the atmospheric discharge, in order to produce up leaders that are faster, steadier and more than the ones in the protected area.
The Leader® lightning conductor used its tip and entire metal consing to capture these disturbances. The disturbances are greatly amplified by a device based on the increase in electrical fields between opposite geometric components and highly inductive systems that regulate electrical disturbances. The significant amplification of electrical disturbances and regulation of leader creation enables the Leader® ESE lightning conductor to produce faster, more powerful and more regular leaders than ali the other leaders in its vicinity. These three characteristics are important safety and operational consistency factors for both positive and negative discharges.
At the time of the atmospheric discharge, the high impedance of the Leader® lightning conductor's inductive and regulator device prevents any current penetration in the lonzing device. The lightning current naturally flows along the outside of the Leader® metal casing, whose impedance is very low. Since the atmospheric discharge never flows through the ionizing device, the Leader® lightning conductor can resist extremely high intensity strikes without altering its ionizing device or its performance.
