Lightning strikes pose a significant threat to tanks, potentially causing damage to electronics, fuel systems, and even endangering crew members. One effective method to mitigate this risk is by employing Discharge Air Terminals (DAS®).
How DAS® Works:
DAS® utilizes the principle of point discharge. When a thunderstorm approaches, the intense electric field in the atmosphere can initiate the formation of upward streamers from the ground. These streamers are precursors to a lightning strike, essentially guiding the downward lightning bolt to the ground.
DAS® strategically placed on the tank disrupt the formation of these upward streamers. By creating a multitude of sharp points, they initiate numerous small discharges into the atmosphere. This multiplicity of discharges effectively neutralizes the intense electric field around the tank, preventing the formation of a single, powerful upward streamer that would attract a lightning strike.
Benefits of Using DAS® for Tank Protection:
- Enhanced Protection: DAS® significantly improves the probability of diverting lightning strikes away from the tank, minimizing the risk of damage.
- Reduced Downtime: By preventing direct lightning strikes, DAS® helps reduce costly repairs and minimize operational downtime.
- Improved Safety: By mitigating the risk of lightning strikes, DAS® enhances the safety of crew members and protects sensitive equipment.
Conclusion:
Incorporating DAS® into the lightning protection strategy for tanks provides a crucial layer of defense against the devastating effects of lightning strikes. By proactively disrupting the formation of upward streamers, DAS® helps ensure the safety and operational readiness of tanks in challenging weather conditions.
