Early Streamer Emission Lightning Protection Systems - What is it?

Early Streamer Emission (ESE) lightning protection systems add an active element to traditional lightning protection. Here are the key components of an ESE system:

●ESE Air Terminal: This is the part mounted on the highest point of a structure. It looks like a pointed rod but has special features to initiate the upward streamer. These features can include multiple points, corona rings, or radioactive elements (though the latter are becoming less common due to safety concerns).

●Downconductor: This is a thick cable that carries the intercepted lightning strike current safely down to the grounding system.

●Grounding System: This network of electrodes buried in the ground disperses the lightning strike current into the earth.

●Control Unit (Optional): Some ESE systems include a control unit that monitors the system’s functionality and may even have data logging capabilities.

Introduction

Advanced technology has changed lightning protection systems for safety and infrastructure protection.LSD, founded in 2005, has led to the creation of new ways to shield buildings and people from natural disasters. This blog post explores one of LSD’s one of the trading products called- Early Streamer Emission Lightning Protection Systems.

What is Early Streamer Emission?

An ESE Lightning Arrester, also known as Early Streamer Emission (ESE) air terminal, is a type of lightning rod that uses an electronic device to emit a controlled upward streamer towards an approaching lightning strike.

Here's how an ESE Lightning Arrester works-

●Energy Gathering: The ESE air terminal, typically mounted on the highest point of a structure, has electrodes that collect ambient electrical field energy as a storm approaches. This field can intensify up to ten thousand volts per meter.

●Storing the Charge: The ESE system stores the collected electrical energy in capacitors within the device.

●Triggering the Upward Streamer: As the storm intensifies, the atmospheric electrical field rapidly increases. This triggers the ESE’s internal device to release the stored energy through its upper electrodes at the tip of the air terminal.

●Initiating the Upward Leader: This released energy initiates an upward streamer, a channel of ionized air, that travels upwards towards the approaching lightning strike.

●Interception and Channeling: Ideally, the upward streamer launched by the ESE air terminal intercepts the downward leader (the lightning strike) initiated from the cloud at an earlier point. This controlled connection channels the lightning strike safely through the ESE air terminal, downconductor, and grounding system, diverting it away from the protected structure.

What are LSD's Early Streamer Emission Lightning Protection Systems?

LSD’s Early Streamer Emission (ESE) Lightning Protection Systems include active ESE Lightning Arrestors. They aim to reduce the harm caused by the high voltage lightning strikes to people and buildings. These devices generate an upward leader faster and more efficiently than traditional lightning rods, enhancing overall lightning protection effectiveness.

The ESE system comprises air terminals, down conductors, and grounding systems. During a thunderstorm, the air terminals produce an upward streamer before anything else nearby. It cut down the time needed to intercept the lightning strike.

Harnessing Early Streamer Emission (ESE) Technology

We employ cutting-edge ionization methods in our Early Streamer Emission Lightning Protection Systems. This proactive approach aims to prevent lightning strikes from becoming too powerful. By doing so, we can reduce the impact of electrical discharges on protected structures.
