TerraStat is the latest design in lightning dissipation technology. Science and experience show that TerraStat Charge Dissipation Terminals, and the structures on which they are installed, are much less likely to sustain a direct lightning strike than unprotected structures or structures with traditional lightning protection systems.
TerraStat®Charge Dissipation Terminals
Securely contribute to ALLTEC’s Protection Pyramid methodology for comprehensive facility protection.
ALLTEC’s clients appreciate that these terminals may be installed under the auspices of UL 96A Master Label lightning protection systems; thus, in the exceptional event of a lightning strike terminating on a CDT, the system meets or exceeds the protection provided by a traditional air terminal.
Whatever your requirements, we have a product to fit the application. For those special applications, we have the capability to design and manufacture a custom system to fit your needs.
To understand how Terrastat® works let us first understand the process involved in a thunderstorm and development of a lightening strike
As a thunderstorm builds, a break down point is reached and the cloud begins sending down charges called ‘stepped leaders’ through ionized paths in the atmosphere. Multiple stepped leaders begin propagating towards the ground in three dimensions looking for the highest accumulation of ground charges in the area. The charges move in steps of approximately 50 mtrs, stop & look for the best potential, then move again. These steps & redirections gives lightening its appearance.
Once the stepped leaders reach within about 10 to 150 mtrs of the earth, objects on the surface where the opposite ground charges have accumulated begin to form upward streamers. The energy from the stepped leaders actually pull the charge off objects on the earth’s surface in the form of upward streamers. At this point, the object on the ground that provides highest concentration of charges and the best formed streamer become the most likely target for the nearest stepped leader and complete the path of lightening strike. Once this occurs, charges from other stepped leaders originating from the same source recede and dump the energy through the established neutralization path. TerraStat is the latest design in lightning technology. They are Provides enhanced performance over traditional lightning protection with patented technolgy.
