Early Streamer Emission System

The principle of operation for Early Streamer Emission (ESE) terminals is to create an upward propagating streamer earlier than conventional air terminals or other objects on the earth. Protec ESE does this by collecting and storing ground charge during the initial phase of a thunderstorm development and emits strong and consistent upwards streamers to intercept leaders.

   Triggering Time Gain   
   The triggering time ΔT (μs) is defined as the gain at the sparkover
   instant obtained with a ESE terminal compared with a simple rod
   terminal exposed to the same conditions.

   Triggering Time Distance Gain
   According to NF C 17-102, The triggering time instance gain ΔT is
   associated with a triggering time distance gain ΔL.

   ΔL = V. ΔT where:

   ΔL (m) : gain in lead distance of the sparkover distance.

   V (m/μs) : the average speed of the downward tracer

   ΔT (μs) : gain in sparkover time of the upward leader

Lightning Protection of Structures
As a general rule for protection, the object to be protected shall be in a LPZ whose electromagnetic characteristics are compatible with the capability of the object to withstand stress causing the damage to be reduced (physical damage, failure of electrical and electronic systems due to over-voltages).

Protection to reduce physical damage and life hazard : The functions of the external LPS are
» to intercept a lightning flash to the structure (with an air-termination system),
» to conduct the lightning current safely to earth (with a down-conductor system),
» to disperse it into the earth (with an earthtermination system) and equalize potential between other earth-termination systems on site (with an isolation spark gap)

Four classes of LPS (I, II, III, IV) are defined as a set of construction rules.

Protection to reduce the failure of internal systems: The protection against LEMP to reduce the risk of failure of internal systems shall limit:
» over-voltages due to lightning flashes to the structure resulting from resistive and inductive coupling;
» over-voltages due to lightning flashes near the structure resulting from inductive coupling;
» over-voltages transmitted by lines connected to the structure due to flashes to or near the lines;
» magnetic field directly coupling with internal systems.

Effective protection against over-voltages, causing failures of internal systems, may be achieved by means of a "coordinated SPD protection", limiting over-voltages below the rated impulse withstand voltage of the system to be protected.

Protec Power Solution has developed the ProESE® product according to internationally recognized standards.
However, Protec Power Solution does not make any specific performance guarantees as no lightning protection system can be 100% effective.
