FINIAL TIPS - ACTIVE
EARLY STREAMER EMISSION (ESE) LIGHTNING ROD
Cu-Tech-Ingesco ESE Lightning Rod provides protection levels
according to the IEC Standards UNE 21.186 and NF C 17-102.
Advantages:
- Completely effective in handling the lightning discharge.
- Carries lightning current without resistance.
- Non-electric lightning rod (self energising).
- No electronics, thus no risk of failure.
- No external power required.
- No special maintenance.
- Certificates of approval.
Function:
The principle of operation is based on the abrupt increase of the
electric field produced by the storm phenomena moments before
a lightning discharge, causing strong ionization directed towards
the cloud. This ionized channel is a path for possible discharge
from the cloud to the ESE tip. When discharged, the lightning bolt
will travel along this ionized path and attach to the desired point
of the ESE. This energy is safely taken to earth. This effect is
directly proportional to the increasing electric field and becomes
more intense before an imminent lightning strike.
ESE design:
A positive charge is accumulated on the loading accumulation
system bars. This allows an early streamer emission of
proportional action to that of the cloud
charge.
Selection:
The protection RADII Rp(m) are
calculated according to
NF C 17-102 pp2.2.3.2
for heights of h=20m.
