The TerraStreamer ESE terminal initiates the upward connecting streamer earlier in time than a traditional lightning air terminal, thus extending the effective range of protection over and above that of conventional lightning air terminals. By utilizing this advanced technology, TerraStreamer ESEs provide lightning protection to facilities that would otherwise be difficult or cost prohibitive to protect by conventional means.

The ESE Principle

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.

1. Thunderstorm begins creating downward step leaders
2. Ambient electric field intensity in the area of the ESE terminal increases
3. Terminal is triggered to release the stored ground charge
4. Upward streamer is formed microseconds earlier than other objects in the immediate area
5. The TerraStreamer ESE terminal becomes 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.

Advantages

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 patented design. TerraStreamer terminals are:

• Externally mounted, proactive, structural lightning protection devices
• Designed to activate in the moments directly preceding an imminent, direct strike
• Tested to certify gain in triggering time (ΔT) as per NF C 17-102 and UNE 21 186
• Designed to ensure that the system provides a secure zone of protection

Protection Performance

The standard protection radius Rp of the TerraStreamer is linked (according to NF C 17-102 standard) to ΔT, to the protection levels I, II, III, or IV and to the height of the TerraStreamer above the protected structure (h, defined by NF C 17-102 as a minimum of 2 m). The NF C 17-102 standard includes four levels of protection.
