In very simple terms, the main difference between passive and active systems is that a passive system is a conductor that sits at the highest point of a structure and is connected to the ground terminal with a heavy-duty cable. The streamer system actively catches lightning bolts and redirects them to the ground spearing lives and property. Here is more info about the principal – on how contemporary ESE lightning rods work. Ideally, these vulnerable points should be selected for lightning air terminal installation.
The lightning air terminal may be raised by an extension mast.
The Down Conductor must be installed straight and vertically in order to provide the shortest and most direct path to earth. Research is a fundamental part of the world of lightning protection. Since lightning phenomenon is very hard to model, analysis must also be based on extensive test campaign. Franklin ro conventional air terminal, or lightning conductor. OPR early streamer emission ( ESE ) air terminals are especially effective for lightning protection of industrial sites, administrative or public buildings, monuments and open-air sites such as sports grounds.
During a storm , when propagation field conditions are favorable, an OPR ESE air terminal will generate an upward leader. Extensive research has allowed ALLTEC to create a lightweight, low wind loading early streamer emission (ESE) system to provide a safe and efficient manner of controlling dangerous lightning energy before it damages a structure or its important contents, including human occupants. We are one of their preferred contractors.
The operating principle is the same as a simple ro but an additional ionization system getting cover a greater protection radius. Every installation shall be reviewed by a prior study to determine the level of protection required (See Figure .1). The theory is that the ionized region will increase the probability. Speak with an Expert Today. The area protected by an ESELC is determined according to its efficiency as defined in Clause 2. The ESELC should preferably be installed on the highest part of the structure.
The emission of an early streamer to a lightning event delivers a beneficial triggering time compared to a single rod air terminal exposed to the same conditions. This in turn drives the enhanced performance and protective distance achievable by ESE devices. It is non-electronicbased lightning protection. Protection systems and means are provided in order to ensure personal safety and to reduce the risk of fire, equipment and systems damages,. The Prevectron early streamer emission device is the preferential point of impact for the lightning discharge and provides the structure with maximum ESE lightning protection.
Standard Compliance Being an active member of major international, European and French standard committees, INDELEC is dedicated to develop fully compliant lightning protection solutions. Lightning Protection Solutions for Every Industry. The testing, as defined in the standar was designed to simulate naturally occurring conditions and allow comparison of the performance between differing types of lightning protection systems. However, the scientific and technical basis for this improved performance is far from certain and the efficacy of these technologies remains open to question.
Early Streamer Emission Terminal.
Dissipation Array System – it’s based on Physics and state-of-the-art engineering. SGI make ESE type lightning protection system TARAN which may hold promise for a more effective protection against lighting. The ionized air produces an electric current flow that weakens the electric field.
This action occurs when the field strength is as low as kV. Current densities of nA.
