DISSIPATION ARRAY® SYSTEM DAS®
Lightning Strike Prevention
DAS® interrupts the formation of upward streamers through point discharge, a phenomenon where a well-grounded point exchanges ions between the air and the ground.
Point discharge becomes more efficient when the points are connected to a low-impedance grounding system, and more ions can be transferred with a greater number of points. DAS technology takes advantage of these principles with an optimal point configuration able to interrupt the formation of upward streamers, thereby preventing direct strikes.
Lightning Protection Components
- The Dissipation Array, available in a range of configurations for almost any structure.
- A low-impedance grounding system using chemically-charged electrodes (Chem-Rod®).
- Transient Voltage Surge Suppression (TVSS) to protect against transients traveling through data lines and other conductive paths.
- Modular strike prevention devices (SBI™) to supplement the Dissipation Array’s area of protection as needed.
