ENHANCED LIGHTNING PROTECTION SYSTEM
LYTECH’s Enhanced Lightning Protection System used Early Streamer Emission Air Terminal (ESE) tested and comply to NFC 17-102 standards.
LYTECH ESE Air Terminal uses the occurring electrical field to release a timely upward leader. This process is a safe and efficient method of capturing dangerous lightning energy at a preferred point.
As a thunder storm gather above the ambient electrical field surroundings, the terminal begins to rise in voltage. As the down leader approaches towards the protected area, there is a rapid increase in the electric field which initiates the triggering of an upward streamer from the terminal.
The use of an E.S.E. Air Terminal protects a larger or enhanced area compared to a conventional rod. With the release of the upward streamer from the finial tip earlier than other competing structural points, the terminal becomes a preferred point for the capture of the lightning discharge within the protected area.
For facilities that already had conventional lightning protection system but continued to face issues resulting from Lightning, LYTECH deploy the ESE Air Terminal to make a hybrid design to complement the existing Conventional Lightning Protection to provide an enhanced protection to the facilities.

Combination of Principles
Direct Strike Protection
The LYTECH E.S.E. Air Terminal uses the occurring electrical field to release a timely upward leader. This process is a safe and efficient method of capturing dangerous lightning energy at a preferred point.
Transient Surge & Overvoltages Protection
As a thunder storm gather above the ambient electrical field surroundings, the terminal begins to rise in voltage. As the down leader approaches towards the protected area, there is a rapid increase in the electric field which initiates the triggering of an upward streamer from the terminal.
Grounding & Earth Grid Systems

With the release of the upward streamer from the finial tip earlier than other competing structural points, the terminal becomes a preferred point for the capture of the lightning discharge within the protected area.

Protection Principles
The protection radius (Rp) of the LYTECH E.S.E. Air Terminal is calculated using the following formula as shown in the French National Standard NF C 17-102.
where ΔT as established in our model
LYTECH E.S.E. 15, T ( μs ) = 15
LYTECH E.S.E. 30, T ( μs ) = 30
LYTECH E.S.E. 60, T ( μs ) = 60
Rp₅ = value of Rp from (1)
h (in meters) = height of the E.S.E. Air Terminal above the subject or area to be protected.
r (in meters) = the chosen level of protection
r = 20m for Level I Protection (Very High Protection)
r = 30m for Level II Protection (High Protection)
r = 45m for Level III Protection (Medium Protection)
r = 60m for Level IV Protection (Standard Protection)
We are pleased to offer our no-obligatory design services to our clients. Just email to us your drawings at sales@lytech.uk and we will do the rest.
E.S.E. Air Terminals
The Air terminal is made from stainless steel which provides protection against corrosion. E.S.E. Lightning Air Terminal meets the requirements under NFC 17-102 standards.
Lightning Strike Counter
The Lightning Strikes’ count are monitored by LYTECH LEC, which is able to give some information about the intensity of the lightning occurence in the area.
