Early Streamer Emitter Terminals
for structural lightning protection
Extensive research and development has allowed Alltec Corporation to create a lightweight and low wind loading ESE system to provide a safe and efficient manner of controlling dangerous lightning energy before it damages structures or its important contents, including human occupants. By utilizing advanced technology, TerraStreamer® ESEs provide lightning protection to facilities that would otherwise be difficult or cost prohibitive to protect by conventional means.
The TerraStreamer® ESE Terminals are externally mounted, proactive, structural lightning protection devices and are designed to activate in the moments directly preceding an imminent direct strike. The installation of a TerraStreamer® ESE Terminal combines the best advantages of two systems: the direct path to ground of a conventional lightning protection system, and state-of-the-art ESE technology employed in the TerraStreamer’s internal design. These combined advantages ensure that the TerraStreamer® ESE System provides a secure zone of protection.
TerraStreamer® ESEs are made of non-corrosive materials, utilize advance and sustainable technologies, maintain a 5-year replacement warranty, and are independently tested certified to NF C 17-102 and UNE 21 186 standards. TerraStreamer® products complete the Alltec Protection Pyramid by capturing dangerous lightning discharges and safely channeling it to earth.

ESE Principles
Read About Early Streamer Emitter Protection Theory
The principle of operation for ESE terminals is to create an upward propagating streamer earlier than conventional air terminals or other objects on the earth. TerraStreamer® does this by collecting and storing ground charge during the initial phase of a thunderstorm development.
Once a thunderstorm begins creating downward step leaders, the ambient electric field intensity in the area of the ESE terminal increases. When this electric field intensifies, it triggers the terminal to release the stored ground charge, forming an upward streamer microseconds earlier than other objects in the immediate area.
This development of an upward streamer earlier in time and space ensures that the TerraStreamer® ESE terminal will be the target of the developing lightning strike. The selection of the TerraStreamer® model, placement, and mounting height above the protected area all factor into formulas calculating the dimensions of the protection area.
ESE Protection Radius
Read About Early Streamer Emitter Protection Radius
Any charts, drawings, or data pertaining to the radius of protection are provided as per the NF C 17-102 standard. According to NF C 17-102, the standard protection radius Rp of the TerraStreamer® is linked to &916;T, the protection levels I, II, or III (as calculated in Annex B of NFC17-102), and to the height of the TerraStreamer® above the protected structure (H, defined by NF C 17-102 as a minimum of 2m).
Alltec has developed the TerraStreamer® product according to internationally recognized standards. However, Alltec does not make any specific performance guarantees as no lightning protection system can be 100% effective.
