Lightning Arrester
A lightning arrester, also referred to as a surge arrester or lightning diverter, is a protective device designed to safeguard electrical systems from the damaging effects of lightning strikes and power surges.
How It Works:
- The arrester is installed at strategic points in the electrical system, such as at the top of buildings, substations, or near critical equipment.
- During a lightning strike or surge, the arrester provides a low-resistance path for the high-voltage current to safely discharge into the ground, thereby protecting the connected equipment.
Key Features:
- High Surge Capability: Can handle extreme voltage surges caused by lightning strikes.
- Durability: Built to withstand harsh environmental conditions.
- Fast Response Time: Reacts instantly to surges, minimizing damage to electrical systems.
- Self-Restoring: Resumes normal operation after diverting a surge.
Advanced Lightning Arrester
Yes, an Advanced Lightning Arrester, or Early Streamer Emission (ESE) Lightning Arrester, is designed to provide proactive lightning protection by emitting an early upward leader before a natural downward leader can reach the structure. This controlled initiation enhances the protection radius and efficiency of the system.
Key Features of ESE Lightning Arresters:
- Proactive Protection – Unlike conventional lightning rods, ESE arresters actively generate an early streamer, increasing the probability of capturing lightning.
- Extended Protection Radius – ESE systems offer a larger coverage area compared to traditional Franklin rods.
- Fast Response Time – The emission of the early streamer reduces the response time, ensuring faster interception of lightning.
- Efficient Grounding System – Once the strike is captured, the arrester safely channels the lightning energy to the ground, preventing damage to structures.
- Durability & Weather Resistance – These devices are built with corrosion-resistant materials for long-lasting performance in harsh weather conditions.
