LECTROTECH - Early Streamer Lightning Rod

LIGHTNING STRIKE COUNTER
The Lightning Strike Counter detects the electrical energy that emanates from a lightning strike as it goes to ground via the down conductor. The device registers each strike increasing the count by one each time. There is no power source required as it uses the induced voltage of the lightning strike for its operation.
Register capacity 999 impulses, 1kA (8/20us), 100kA (10/350us), IP65, IEC 6256106 Standard.

Code: P-CDR-UNIVERSAL
The lightning counter detects lightning
strikes on any external lightning protection system e.g. lightning rods, ESE, Faraday cages etc. It operates independently of protection status or the quality of the counter fastening to the down conductor.

Code: P-CDR-11
The lightning counter detects lightning
strikes on any external lightning protection
system e.g. lightning rods, ESE, Faraday
cages etc.

Code: P-CDR-HS
High sensitivity lightning strike counter.
Used on protection systems such as
conductive mesh or down conductors in
contact with metal walls.

 
ESE INSTALLATION (GUIDE)
Full installation must be in accordance with standards UNE 21.186 & NF C 17-102

CAPTURE SYSTEM
- The top of the ESE must be 5m above the zone it protects. ( including antennas, cooling towers etc).
- Any receiving antennas (TV, radio, telephone) must be connected to the
down conductors via a spark gap.
- The coaxial cables of these antennas
must be protected with an appropriate
surge protection device.
- Any metallic items that rise above the
roof level must be bonded to the
closest down conductor.

DOWN CONDUCTOR SYSTEM
- Each ESE must be connected to at least one down conductor. At least two down conductors are required for the following cases:
- If the width and breadth of the structure is larger than the height.
- Where the height of the structure is greater than 28 m.
- The two down conductors must be located on the opposite sides of the structure.
- Down conductors must be as straight as possible and the shortest path to the earthing system. Bends not to exceed 20 cm.
- Down conductor must be on the outside of the building and not near electrical or gas pipes.

EARTH SYSTEM
- An earthing system is required for each down conductor.
- The earth resistance must be less
than 10 ohms.
- It is recommended to have an inspection box with a disconnection point such that the earth can be
regularly tested.
- Cross bond the ESE earth(s) to the
structure earth.
