An Early Streamer Emission (ESE) device is a type of lightning protection system designed to protect structures from lightning strikes by intercepting and safely directing the electrical charge into the ground.

Unlike traditional passive lightning protection systems, which are designed to attract lightning by providing a high point where lightning can strike, an ESE lightning conductor aims to create an early interception of the lightning discharge. This system works by emitting an ionized air stream or "early streamer" from the top of the conductor before the main lightning strike reaches a structure. The idea is to provide a safer and more controlled path for the lightning to follow, which helps prevent damage to the protected structure.

 

Here’s how it works in more detail:

​

1. Early Emission: The ESE lightning conductor generates an early streamer or ionized pathway. It does this by emitting an electrical charge that can trigger the lightning discharge before it can strike parts of the building or structure.

2. Attracting Lightning: Once the early streamer is emitted, it creates a controlled path, making it more likely that the lightning will strike the conductor rather than a nearby structure or electrical system.

3. Dissipating Energy: The lightning energy is safely conducted down the conductor and into the ground, minimizing the risk of damage.

 

ESE lightning rods are often considered more efficient in certain situations, especially in areas with a high frequency of lightning strikes, as they help to increase the chances of intercepting a lightning discharge early on, rather than waiting for it to approach the structure.
