DISSIPATION ARRAY® SYSTEM - DAS®

Lightning Prevention System

Don’t just protect against lightning, avoid it altogether to keep you running through the storm


The proprietary Dissipation Array System (DAS) from Lightning Eliminators is a patented solution engineered to prevent lightning strikes instead of just managing their effects.

How it works

Lightning is nature’s way of equalizing the voltage between storm clouds and the earth. For a strike to occur, a connection must be made. Lightning is an electric discharge that attempts to equalize voltage between storm clouds and the earth. The difference in polarity between the bottom of the cloud and the ground is the charge differential. When this charge differential is high, the cloud begins to form downward leaders and objects on the ground begin to form upward streamers. When a leader connects with a streamer, it gives lightning a path for exchanging charge between the earth and the cloud, reducing the charge differential to upward streamers.

The DAS interrupts the formation of these upward streamers through point discharge, a phenomenon where a well-grounded point exchanges ions between the air and the ground. DAS technology interrupts the formation of upward streamers, preventing direct strikes to keep your operations running through the storm.

A Systems Approach

The Dissipation Array System is a key component of your lightning protection system, working with grounding and surge suppression to achieve complete protection. A typical system includes:

  • 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 (Spline Ball Ionizer - SBI™) to supplement the Dissipation Array’s area of protection as needed.

Key Features and Benefits:

  • Total Lightning Prevention. The Dissipation Array System prevents direct lightning strikes within the area of protection.
  • Reduce Operating Costs. Protects against lightning damage, including fires, destroyed electronics, and downtime.
  • Reliable. Our “No-Strike” warranty ensures complete protection on all LEC supervised installations.
  • Universal. Engineered to integrate with any building, tower, tank, stack or other structure.
  • Proven. DAS technology has been in use since 1971, protecting thousands of sites worldwide.
  • No-Strike Warrenty. LEC extends a “Warranty” subject to “terms and conditions” and subject to inspection and maintenance.

Why Choose DAS to Prevent Lightning Strikes

Traditional lightning protection using lightning rods and other technologies are designed to give lightning a controlled pathway to the ground where the electrical charge can be dispersed. Instead of managing a strike, the DAS aims to prevent the likelihood of a strike in the first place.
When used as part of a comprehensive Lightning Defense strategy, the DAS provides your operations and personnel the strongest defense against lightning related risks and keeps you running through the storm.
